Question

If the point (3/5 , 4/5) corresponds to an angle 0 in the unit circle, what is the tan 0?

Answer 1

Given the circumstances, a triangle can be drawn on a circle where the hypothenuse is 5, the leg going right is 4, and the amount going up is 3 (Try visualizing it). Knowing that tangent is opposite over adjacent of theta, tangent would be 3/4
