2+cos(x)=2

2 + cos (x) = 2

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

Solution steps

2 + cos (x) = 2

Subtract

2

from both sides

2 + cos (x) - 2 = 2 - 2

Simplify

cos (x) = 0

General solutions for

cos (x) = 0

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

cos (\frac{π}{2} + x) = 0

4.1 = 4.2 cos (18 t) + 3

4 sin (x) - 13 = 2 cos^{2} (x) - 9

cos (θ) = - \frac{8}{11}

sin (θ) = \frac{3}{12}
