Use the unit circle to evaluate the trigonometric functions, if possible. cotπ2
Added by Danielle F.
Step 1
So, we need to find the tangent of π/2 and then take its reciprocal. The point on the unit circle corresponding to π/2 is (0,1), which means that the y-coordinate is 1 and the x-coordinate is 0. The tangent of π/2 is defined as the ratio of the opposite side Show more…
