Question

how do you find the cotangent of 7pi/6

Answer 1

with or without a calculator?

Answer 2

using the unit circle?

Answer 3

cotangent is actually 1/tan so all you do is find the tan of 7pi/6 (sin/cos) which is sqrt3/3 and since the cotanget is 1/tan all u do is flip it so you get 3/sqrt3
but since u cant have a square root on the bottom u mult both to and bottom by sqrt3 so u get 3sqrt3/3...finally u can cancel the 3s giving u a final answer of just sqrt3

Answer 4

thank you!
