Well that is all well and good but then please explain to me how I could approximate these values.

I realize that the x and y cordinates are the definitions of cosine and sine. My quarrel is how do i determine the x and y values. What I meant by derive was how do i come up with the x and y values for this triangle and for all rational degrees around the circle so i can sketch a sine wave...

So I know that sine of an angle is the side opposite of the angle in a right triangle divided by the hypotenuse. What i want to know is: if i have an angle in a right triangle how do i find the sides of the triangle so i can find Sine. I spent my study hall trying to figure it out and this is...
