Had a real hard time learning trig in school. It was only until I learned what the real world use of it was that I actual understood it. I remember asking the teacher back in high school what it was use for only to be directed to a posted hung on the wall that was a chart with what careers used what types of math, Out of likely 30 careers listed trig was only indicated on math teacher and rocket scientist. What an udder fail. I'm sure if I grew up in a manufacturing heavy city 50 years ago I would have had no issues learning it as it was be taught practically how it was actually used.

My last Math Teacher "handed me the tools" he made me see it.. and from that moment on, i was able to calculate Cartesian coordinates from drawings with polar dimensions, i could calculate the trail of a motorbike, by measuring the Fork angle, the offset, Fork length and wheel diameter.. all of the sudden.. these things couldn't hide their secrets from me..

Having been married 4 times and this last one for over 20 years... I finally figured it out. I mean how to get your wife to WANT you to buy toys... I mean tools. Make stuff for her. It's that simple. Or in order for you to do something that she wants, show her how this new tool (insert any damn tool you need) will help you do what she WANTS you to do. OH, and it does help if you bring her to your working area and let her watch you do some magical thing like cutting a special thread on a small part. OH... I forgot to tell you. If by chance you are one of those who believe that opposites attract... that isn't love its lust. so... Hopefully you were smarter than I was and you only married once and she has A LOT in common with you. Then she will understand exactly what the hell you are doing and why. That way, when you say "Honey, how about we go to Woodcraft and look at the wood lathes." and she says..." How about we go to Woodcraft and buy a wood lathe." You will know you have chosen wisely... BUT... be damn sure you make stuff for her!!! Now. How did I get my first metal lathe? I had a great rifle that I loved but I found a South Bend 9A lathe that I wanted more. I traded. Here is the small lesson. If you sell something, use that money to buy something to replace it. Similarly, if you are going to trade something, trade it for something you are going to replace it with. I had a great rifle that my grandpa had given me so the ole 30.06 just wasn't needed any more. hence my new lathe. Good hunting!! OH, and in case I forgot to mention it... make stuff for her!!!

Man you got it all wrong! Sine is what your kid does at the bank when they want to buy a car and promises to pay for it, cosine is what the bank makes you do so they give your kid a loan for the car, then cosine error is when the cosine ends up paying for the car because the sine didn't make the payments. And that my friends is why a sine bar looks like a little car with a rear spoiler.

When public education is forced funded and education is mandated, it is no surprise the quality and usefulness goes down. Consider that many public schools are also daycare centers and indoctrinate siphoning funds away from real useful practical education. Consider universities mandating all sorts of diversity classes and such to get a degree. It is indoctrination coupled with a type of extortion. Consider people taking classes for what they want to learn are more likely to work to learn. Likewise when parents and guardians are involved with their children's education, the children are more likely to learn. School choice is a step in a better direction.

The problem teachers face with this kind of dry subject is putting it into a context that students will be interested in and concentrate. Viewers of this old channel are interested in making lumps of metal different shapes. Tony can use applicable examples to show how it all works which makes the information bit more interesting and you engage more. In a class of 30 to 40 students, very few of them will have a similar set of interests, so teachers are limited in how to show what they are teaching in a real world setting. This gives rise to people saying 'when will I ever use this crap after I leave school?. In a job I had many years ago I had to help a guy set CCTV cameras up to monitor banks of slot machines for a couple of days whilst his assistant was out sick. Now how they used to do it was one would watch the monitor whilst the other would tweak settings and lenses on the camera. This seemed like a long winded way to so it. So I asked if we could try one camera my way, with that evening's beers riding on the success of my idea. I took the tape measure and measured the length of the bank on slot machines, the height of them, the height of the ceiling, and the angle of the lens' field of view. Then using a bit of trigonometry, worked out how far away from the machines the camera should be located, the angle from the machines both in relation to the ceiling and to the bank of machines. Armed with may calculations, I measured out where the camera was to be located and mounted it, used an old school protractor to set the angles and hooked up the cable. The only tweak we needed was to focus the camera and then agree to what time my colleague would be getting the first beer in. It took about 1/5th of the time they used to take and as far as I know, they're still using my method and enjoying longer breaks because they 'forgot' to tell our manager they found a quicker way to do the job. Even the strangest maths taught in school can crop up in every day life.

one of the coolest explanations EVER on this topic. i have brushed shoulders with many instructors in many schools of thought, college full time at 15yrs old, trade school in California, IBEW trade school in Missouri, Technical school in Tennessee, and now a deep yerning to learn machinists theory and protocals considering all the equiptment i have aquired over the years for 'pipe-dream' projects. i have never heard such perfect, easy to understand, examples of trig functions...ever. WELL DONE. thank you very much for your videos sir. Precise, reasoning, humor, examples, ect., perfect mix.

"We learned something here today." -Kyle And, it reinforced for me why my Dad, the Engineer, always spoke reverently about individual machinists, with whom he interacted. Also, I should note that concepts and relevance discovered earning Surveying Merit Badge saved me when faced with High School geometry, algebra and trig. When I was in school, so much was apparently irrelevant. It wouldn't have taken much to tie it to usefulness, which would have helped with motivation and understanding. Thanks, Tony.

Almost sixty years ago, I started my freshman year of college as an engineering student. I loved math, science, precision, etc., so I figured I should be some type of engineer. Then two things happened simultaneously. First, I joined a college fraternity. Second, I began my first trig course. I quickly discovered that the curve a beer mug makes from a bar top to my lips was easier to calculate--intuitive, in fact--than the angles involved in trig. At the time, of course, the beer mug and the social life that went with it seemed much more important than trig, so I changed my major to sociology. Sociology, as every sociology graduate knows, is a vocationally worthless diploma. Live and learn. Looking back, I can see that I would have benefited from a lot more precision in my decision-making process at the time, but somehow I survived until today without ever mastering trig. Anyway, your video brought back all the old pain--and fascination--that I once found in trig, and reminded me what a dumbass I was to drop out of engineering. Thanks for an entertaining and instructive video explanation of trig--something I should have taken the time and made the effort to learn, way back in 1966.

When TOT got out his flashlight and said “let me shine my flashlight in this,” or whatever it was he said, the flashlight on my iPhone turned on. I went back a few seconds and tried again, but I guess it was just a fluke. We’ll actually it wasn’t a fluke. A fluke is an electrical meter and I have one because I’m an electrician and not a machinist. We also use trig when we’re calculating power factors or bending conduit. Usually the latter because the power factor is already calculated by the equipment manufacturer and we just install the thing. And actually it isn’t the latter. A ladder is what tradesmen who don’t spend their lives in machine shops use when they need to install something that’s higher than they are tall, that, and you get bad luck for walking under them because of trig.

The problem is that most trig isn't related to anything a 14 year old would care about. Knowing how triangles, circles, and graphs are related is really important for understanding trig, but all the real world examples are either weird, contrived situations or way too complex to clearly get the concept across

This is yet more evidence supporting my hypothesis that schools COULD teach us math if they wanted, they just don't. It's like some sort of sorting mechanism, trying to find the one student in thousands (or more) that might grow up to be a theoretical mathematician and make the next non-Euclidian-geometry-level discovery. Meanwhile, I have spent most of my life terrified of math and struggling with basic arithmetic. God, I hate the school system.

Why would it be called cosine error when the value you get is related to 1/cos= secant of the angle between the measuring tool and the line segment being measured. Even so, the measurement error is sometimes expressed as a range of values which is related to the derivative of sec t, which is sec(t)tan(t) so it should be called the secant-tangent error or sine-by-cosine-squared error. People will surely like that name much more.
