Calculate . The answer may contain roots but not trigonometric functions.
im really bad on the geometry so any1 give me tips?

Hint: where .
i want the range 0 ≤ x < 2π, so i have to choose k so it will be on tat range so k= 4 if i got right,sorry kkkeybord broken
so you have:
ty again! but how can ik what cot 5pi/6 is on test
nvm solved it
cot (5π/6) = 1 / tan (5π/6) = - 1/√3
You should know (or be able to quickly find using the unit circle):
If you prefer to use a first quadrant angle, then you may write:
