SUMMARY

The equation to solve is cot x = (3)^(1/4), leading to the derived solutions x = pi/6 and x = 5pi/6 within the interval [0, 2pi). The process involves squaring both sides of the equation, resulting in cot^2 x = 3, which simplifies to cot x = ±sqrt(3). However, only the positive root is valid due to the square root in the original equation, eliminating the negative solution and confirming the final answers.

PREREQUISITES
  • Understanding of trigonometric functions, specifically cotangent.

Homework Statement



Solve, finding all solutions in [0, 2pi)

Homework Equations



sqrt (cot x) = (3)^(1/4)

The Attempt at a Solution



[sqrt (cot x) = (3)^(1/4)]^4 =

sqrt [cot^2 x = 3] =

cot x = +/- sqrt (3)

x = pi/6, 5pi/6, 7pi/6, 11pi/6

the answer choices to this problem only have two angles each, so two of the angles I derived aren't necessary
