but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.

This applet shows how the graphs of sin(θ) and cos(θ) follow directly from the definition of these functions. Move the slider to change the angle. Observe that after the point moves once around the ...
