cosine and sine..
Find all angles t, where 0 < or = t < 2pi, that satisfy the given condition.
a) cost = 1
b) sint = 1/2
Find all angles theta (symbol), where 0° < or = theta < 360°, that satisfy the given condition.
a) sin theta = 1/2
b) cos theta = 1
I kinda forgot how to find these, any help appreciated. Don't really remember the special triangles if that's what's needed to solve these.. ><.
Explanations and steps would really help, thanks a lot.

$\displaystyle \sin (\theta) = \sin (2n\pi + \theta)$
$\displaystyle \sin (\theta) = \sin ((2n+1)\pi  \theta)$
