Deriving Values on the Unit Circle

Deriving Values on the Unit Circle. In this video, I show how to actually DERIVE the values in the first quadrant of the unit circle (so that you are not just memorizing them!). All you are really doing is using a bit of geometry and the pythagorean theorem; nothing worse than that!
**Sorry! The table shakes a bit! I am not at home using my usual set up and I have a shaky table - trying to figure out how to make it more stable!**

@ThaEther ha ; )

This makes math rational.

Fantastic! I could listen to you all day.

it was awesome, thank you. but pls use the 30 60 90 rules man! come on! we need help but we are not math-tards. AWESOME video i just think that you took too much time explaining how to figure out 30 60 90 and 45 45 90 triangles

my favorite video. <3

How do you derive the coordinates of say, pi/5 or pi/7? How can we prove the coordinates of, say, 34 degrees or 96 degrees? Please help. Thanks.

Thank you very much. Your instructions are so helpful in refreshing myself on trig while in calculus.

i love you.

its amazing how my teacher introduced this to us the day after you posted this! thanks for the heads up xD
