-4cos^2(x)=0

- 4 cos^{2} (x) = 0

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

Solution steps

- 4 cos^{2} (x) = 0

Divide both sides by

- 4

cos (x) = 0

General solutions for

cos (x) = 0

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

sin^{2} (x) - 4 sin^{2} (x) + 7 cos^{2} (x) = 0

(sin (x)) (cos (x)) = 0

sin^{2} (x) - 15 sin (x) cos (x) + 50 cos^{2} (x) = 0

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

sec (2 x + 60) = - 1.5
