I have just subscribed to your channel. I am a retired scientist(hydrogeochemical), a chemistry degree of about 50 years ago. I did calculus and algebra but have used just a little. Now, I have to help my grandkids to get into University and they want to be engineers and scientists. No problem to help them in chemistry and physics but Advanced Maths to prepare them for Calculus is a great pain. I have been avoiding it until now. Universities in Australia have Advance Maths plus Extension as a pre-requisite. Consequently, I have no choice but to review pre-calculus and calculus. So far I have really enjoyed your presentations and advice: "Do not do in your head but worked out in the paper" Great advice! I like the way you teach and present the topics. I am catching up and teaching my grandson for his preparation. Thank you very much, Professor Leonard. Still have 3 granddaughters and 2 grandsons waiting their turn.

I got extremely stuck on Trigonometry during an optional math course in high school about 20 years ago, and dropped out of that course. But I did find math really fun, so I actually started reteaching myself as much as possible from all the previous math courses from junior high school and onward, and made absolutely sure that I understood exactly what I was doing, and this then allowed me to finish Trigonometry, and at this point I have covered all of Professor Leonard's playlists, as well as studied some partial differential equations and fluid dynamics at university. It's really a lot about regularly reviewing stuff, and keeping an eye on both old and new material. It's also a good habit to try to derive laws and formulas on your own, since this shows that you know where they come from and how they work, and also guarantees that you always have access to them.

For those confused as to why (x+1)^2 = x^2 + 2x + 1 Here is why it is since he brushed past it a bit. the expression (x+1)^2 = (x+1)(x+1) meaning (x + 1) times itself. Which means you would take (x)(x) and get x^2 and (x)(1) = x and (1)(x) = x then (1)(1) = 1 If you simplify you would combine x + x which equals 2x Then your answer would become x^2 + 2x + 1

Function names don't have to be limited to g(x) or f(x) or even h(x) but you could even use words. It's definitely not common in math but there is no reason you couldn't. It is common in programming and you see that in graphing calculators. Ever seen a function named sqrt() instead of f(x)? You could do the same thing and write sqrt(x) = √x although I can't type the full symbol on my phone but you get the idea. Now to really blow your mind, there is no reason you couldn't use a symbol like an emoji for the function name. You could do 😀(x) = x*x to represent a function that squares a number.
