cot^2(θ)-cot(θ)=0

cot^{2} (θ) - cot (θ) = 0

θ = \frac{π}{4} + πn, θ = \frac{π}{2} + πn

Solution steps

cot^{2} (θ) - cot (θ) = 0

Solve by substitution

cot (θ) = 1, cot (θ) = 0

cot (θ) = 1 : θ = \frac{π}{4} + πn

cot (θ) = 0 : θ = \frac{π}{2} + πn

Combine all the solutions

θ = \frac{π}{4} + πn, θ = \frac{π}{2} + πn

5 cos (2 θ) = - 15 cos (θ) - 10

2 cos (x) - 5 = 3 sec (x)

sin (3 θ + \frac{π}{18}) = 1, 0 \leq θ < 2 π

1 = tan (c)

sin (a) = \frac{3}{2}
