Question

Find the exact value of the trigonometric function.

Answer 1

cot\[(-\frac{ 5\pi }{4})\]

Answer 2

Its pretty simple when you get it, first find -5pi/4 on your unit circle, remember to go clockwise this time and find the sin and cos values for 5pi/4

Answer 3

So since it is negative you go clockwise and locate 5pi/4, well anything on the unit circle with a denominator of 4 is root 2/2 right?

Answer 4

so sin and cos equal sqrt(2)/2 and now we use cot as cos/sin
