    As I said in the other thread, tan is tangent, just to clear anything up. Second, Tan(theta) = y/x (if we're talking about right triangles). Theta = arctan(y/x). Same applies for sine and cosine. The value for theta is based on the y/x. So arctan(1/2) is 30 degrees. Arccos(1/sqrt2) is 45 degrees.

    You definitely need to know the cos/tan/sin relationships with a right triangle. Knowing values of common angles (0,30,45,60,90 degrees) is probably a good idea.

    I think I know which problem in 3R you are talking about. If it is the one I am thinking about, you didn't need to know the numerical values for angles, just the relationships.
