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

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

x = π + 2 πn

Solution steps

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

Solve by substitution

cos (x) = - 1

cos (x) = - 1 : x = π + 2 πn

Combine all the solutions

x = π + 2 πn

7 tan (θ) = 23 + tan (θ)

sin (x) sin (\frac{x}{2}) = 1 - cos (x)

24 tan^{2} (x) - 8 = 0

2 sin (x - \frac{π}{3}) = 1

tan (θ) = 2.7
