cos(θ)+1=1

cos (θ) + 1 = 1

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Solution steps

cos (θ) + 1 = 1

Subtract

1

from both sides

cos (θ) + 1 - 1 = 1 - 1

Simplify

cos (θ) = 0

General solutions for

cos (θ) = 0

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

9 cos (x) tan (x) = - 8 tan (x)

2 sin^{2} (x) + cos (x) = 2

sin (x) cos (x) = - 9 cos (x)

5 tan (θ) - 7 = 0

cot^{2} (x) + 1 = sin^{2} (x)
