cos(x)+7=7

cos (x) + 7 = 7

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

Solution steps

cos (x) + 7 = 7

Subtract

7

from both sides

cos (x) + 7 - 7 = 7 - 7

Simplify

cos (x) = 0

General solutions for

cos (x) = 0

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

6 sin^{2} (x) + 4 sin (x) - 1 = 0

cos (x - \frac{π}{4}) + sin (x + \frac{π}{4}) = 0

3 tan (x) + 1 = 0

cos (2 x) = \frac{7}{25}

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