2cos(θ)-3=-5,0<= θ<2pi

2 cos (θ) - 3 = - 5, 0 \leq θ < 2 π

θ = π

Solution steps

2 cos (θ) - 3 = - 5, 0 \leq θ < 2 π

Move

3

to the right side

2 cos (θ) = - 2

Divide both sides by

2

cos (θ) = - 1

General solutions for

cos (θ) = - 1

θ = π + 2 πn

Solutions for the range

0 \leq θ < 2 π

θ = π

2 tan (x) + 1 = 0

2 cos (3 x) + cos (2 x) + 1 = 0, 0 \leq x \leq 2 π

tan^{2} (x) = 3

tan (x) csc^{2} (x) - 2 tan (x) = 0

5 sin (2 x) = cos (x)
