-1-2sec^2(x)=-3sec^2(x)

- 1 - 2 sec^{2} (x) = - 3 sec^{2} (x)

x = 2 πn, x = π + 2 πn

Solution steps

- 1 - 2 sec^{2} (x) = - 3 sec^{2} (x)

Solve by substitution

sec (x) = 1, sec (x) = - 1

sec (x) = 1 : x = 2 πn

sec (x) = - 1 : x = π + 2 πn

Combine all the solutions

x = 2 πn, x = π + 2 πn

tanh (x + 1) + 1 = 2

sin (2 θ) = 0.9076

7 sin (B) + 3 = sin (B) + 2

4 cos (x) = 3

cos (x + \frac{1}{6} π) cos (x - \frac{1}{6} π) = cos (2 x)
