Why is cos (180°) = -1 and sin (180°) = 0?
What is it's the point where the unit circle intersects with the negative x-axis, or the angle that lies directly opposite 0° and coordinates that are (-1,0), furthest point left on the unit circle.

What is the exact value of csc (330°) on the unit circle?
What is -2
Why is tan (90°) undefined, and why does it happen?
What is because tan (theta) = sin (theta)/cos (theta), 90° - sin (90°) = 1 but cos (90°) = 0, because you're dividing by 0, causing a tangent function to be undefined at 90°.
