Question

Solve 3cotx - √3 = 0 for 0 ≤ x < 2π.

Answer 1

• 3cotx-√3=0
• 3cotx=√3

Divide both sides by √3

• √3cotx=1
• cotx=1/√3

Solution set of x values in between 2π is

• {60,120}

Answer 2

Solution given:

3cotx - √3 = 0

3cotx=√3

cotx=√3/3

cotx=1/√3

1/tanx=1/√3

tanx =√3

tanx=tan60°,tan240°,

:.x=60°,120° or π/60,3π/4
