6-cos^2(θ)=5

6 - cos^{2} (θ) = 5

θ = 2 πn, θ = π + 2 πn

Solution steps

6 - cos^{2} (θ) = 5

Solve by substitution

cos (θ) = 1, cos (θ) = - 1

cos (θ) = 1 : θ = 2 πn

cos (θ) = - 1 : θ = π + 2 πn

Combine all the solutions

θ = 2 πn, θ = π + 2 πn

2 sec (x) + 2 = 6

14928 = \frac{18177}{( 1 + 0.387 cos ( x ) )}

sin^{2} (θ) - 3 cos (θ) = 4

sec^{2} (x) - 2 = 0, 0 \leq x \leq 2 π

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