sin^2(x)cos^2(x)=0

sin^{2} (x) cos^{2} (x) = 0

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

Solution steps

sin^{2} (x) cos^{2} (x) = 0

Solving each part separately

sin^{2} (x) = 0 or cos^{2} (x) = 0

sin^{2} (x) = 0 : x = 2 πn, x = π + 2 πn

cos^{2} (x) = 0 : x = \frac{π}{2} + 2 πn, x = \frac{3 π}{2} + 2 πn

Combine all the solutions

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

3 sin (x) cos (x) + 5 cos (x) = 0

5 sin (x) tan (x) = - 7 tan (x)

cos (x + \frac{π}{2}) - cos (x - \frac{π}{2}) = 2

tan (2 x) + 1 = sec (2 x)

sin (x) \cdot cos (x) = 0
