**Sin Pi**

### Why is sin equal to pi?

Another interpretation of the sign and cosine is that, on the unit sphere, the synx represents the y-coordinate of the point, while the coaxial point represents the x-coordinate. When you draw the circle of the unit, the point that makes the 180 degree angle is (1.0). So sin (180) = 0

No z

pi is in radians and is equal to 180 degrees. If you graph it, you can clearly see that the value of the current action is 0.

Note that sin (x) is the height of an angle triangle, which has angles x and hyenas 1.

If you draw a triangle, you will see that it has no height, so sin (x) = 0. (a triangle is really just a line)

Hmmm ... a philosophical question. We will see...

why not?
