3cos(x)+1=1

3 cos (x) + 1 = 1

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

Solution steps

3 cos (x) + 1 = 1

Subtract

1

from both sides

3 cos (x) + 1 - 1 = 1 - 1

Simplify

3 cos (x) = 0

Divide both sides by

3

cos (x) = 0

General solutions for

cos (x) = 0

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

sin (θ - \frac{π}{3}) + 1 = 0

tan^{2} (2 θ) = tan (2 θ)

2 cos (2 x) = 2 sin (x)

- sin (θ) + 1 + cos (θ) = 0

sin (x) = \frac{1}{10}
