5cos(A)+8=3cos(A)+6

5 cos (A) + 8 = 3 cos (A) + 6

A = π + 2 πn

Solution steps

5 cos (A) + 8 = 3 cos (A) + 6

Solve by substitution

cos (A) = - 1

cos (A) = - 1 : A = π + 2 πn

Combine all the solutions

A = π + 2 πn

2 + 7 cos (θ) = 4 sin^{2} (θ), - 18 0^{\circ} \leq x \leq 18 0^{\circ}

1 = 2 cos (3 θ)

cos (4 θ) + cos (2 θ) = cos (θ)

(tan (x) + 3) (tan (x) + 2) = 0

2 tan (θ) + 6 = 0
