Question

how do you find the cotangent of 5pi/4 on the unit circle

Answer 1

find the tangent of 5pi/4 and then take the reciprocal...

its a 3rd quadrant angle...

Answer 2

since tan = opp/adj

then cot = adj/opp

Answer 3

so you are basically finding the and pi/4

and th e answer is 1 since tan(pi/4) = 1, the cotangent is 1

Answer 4

Find the exact value of cot 240° using the unit circle. Rationalize the denominator, if necessary

Answer 5

cot(240) = cot(60)

so find tan(60)

then take the reciprocal.
