758,758 | I am learning about radians in my current class and am totally confused.
How does $\sin(x+\frac\pi 2)=\cos(x)$ when $\frac\pi 2<x$ < $\pi$.
I drew the triangles and I got
$\sin(x+\frac\pi 2)=\frac{-\mathrm{opposite}}{-\mathrm{hypotenuse}}=\frac{\mathrm{opp}}{\mathrm{hyp}}$
$\cos(x)=\frac{\mathrm{adjacent}}{\mathrm{... | 2014/04/18 | [

] | Your expression for $\sin(x)$ is correct. But recall that the cosine is the abscissa divided by the radius of the circle. So in your drawing, $\cos(x)=\frac a b$.
