The unit circle is just a way of adding 30ths and fifteens to the number that comes immediately before it in order to get the next number After zero we add 30 After 30 we add 15 to get 45 After 60 we add 30 to get 90 After 90 we add 30 to get 120 After 120 we add 30 to get150 after 150 we add 30 to get180 After 180 we add 30 to het 210 After 240 we add 30 to get 270 After 270 we add 30 to get 300 After 300 we add 30 to get 330 After 330 we add 30 to get 360 The addition of fifteens comes inbetween The numbers directly before and after 0, 90 180 270. We add thirties To all the others we add fifteens 30, 150 210 330 all have sine and cosine coordinates of square roots of three over two and 1/2 ...... In some variations or other depending on which quadrant they are in they may be positive or negative Remember that sine is mapped to the Y axis while cosine is on the X axis ( COSINE, SINE) This way you can learn the unit circle just by adding fifteens and thirties to preceeding numbers to get the current number if you study it a bit Not want to bore you anymore by teaching you many more methods to learn the unit circle I am Richard Michaels Younger brother of Shereen Michaels and I am a student at SUNY in New York USA Cant give out my email address here Too public Would love to help more if I could Sorry

Better way to memorize this, Sin30 = 1/2 Sin45 = sqrt2/2 Sin60 = sqrt3/2 Cosine is just the opposite, Cos60 = 1/2 Cos45 = sqrt2/2 Cos30 = sqrt3/2. If you look at this the Sin values goes from least to greatest, and Cosine values goes from greatest to least. Regarding Tangent, its just Y (sin) /X (cosine) or Opposite / Adjacent, Tan30 = 1/sqrt3 = sqrt3/3 Tan45 = sqrt2/2 / sqrt2/2 = 1 Tan60 =sqrt3/2 / 1/2 = sqrt3 For reference angles just remember if the given angle is closer to 180 or 360 degrees or Pi / 2pi. When in radians for example if given Cos(2pi/3) you can ignore the 2 and just focus on pi/3 since thats the reference angle. Thus becoming Cos(pi/3) = -1/2 since quadrant 2. Remember your Quadrants Q1,Q2,Q3,Q4 and also just remember A S T C regarding the positive values for the trig functions.

Around 9:20 you wrote that the hypotenuse = 2 for the 30-60-90 degree triangle. This is incorrect. The hypotenuse of a triangle on the unit circle is always = 1 because the radius of a unit circle is always equal to one. Also the 30-60-90 degree triangle is half an equilateral triangle. So given that hypotenuse = 1 (since the triangle is on the unit circle) and Pythagorean theorem you can get the other sides. So the sides of 30-60-90 degree triangle on unit circle are: hypotenuse = 1 Side = 1/2 Other side = (sq. rt. 3)/2. Same hypotenuse = 1 concept applies to 45-45-90 degree triangle since it’s on the unit circle. This means that hypotenuse for 45-45-90 degree triangle is (x)(sq. rt. 2) = 1. And the two other sides of 45-45-90 degree triangle are each 1/(sq. rt.2).

Although yes, you are right, it doesn't really matter in this case what is on top and bottom as the ratio is the same.

I prefer use the rule of "Use sempre sua cabeça", or USTC. That's a portuguese shortcut to know where is the signal from the cos sin ou tan of a given angle If the angle is from the 1st quadrant, it's always positive from the 2th, only the sin will be positive the 3th, the tangent and the 4th, the cos Of course, your way is very practical to lear if we are dealing with non exact angles (like tan of 572 degrees, which can be expressed in radians instead of degrees). To sum up It could be useful kowing how to use both of them!
