2+cos^2(x)=-3cos(x)

2 + cos^{2} (x) = - 3 cos (x)

x = π + 2 πn

Solution steps

2 + cos^{2} (x) = - 3 cos (x)

Solve by substitution

cos (x) = - 1, cos (x) = - 2

cos (x) = - 1 : x = π + 2 πn

cos (x) = - 2 :

6 sec^{2} (x) + tan (x) - 7 = 0

4 \cdot sin^{2} (x) = 3

cos (B) = \frac{2}{3}

tan (θ) sin (θ) = 3 sin (θ)

sin (2 x) = 1 - sin (2 x)
