2(cos(x)+3)=5+cos(x)

2 (cos (x) + 3) = 5 + cos (x)

x = π + 2 πn

Solution steps

2 (cos (x) + 3) = 5 + cos (x)

Solve by substitution

cos (x) = - 1

cos (x) = - 1 : x = π + 2 πn

Combine all the solutions

x = π + 2 πn

4 cos (3 x) - 1 = 2 sin (3 x) tan (3 x)

tan (θ) = \frac{15}{20}

- cos (x) = 0.9

3 cos (θ) - 2 sin (θ) cos (θ) = 0

sec (x) + sin^{2} (x) + cos^{2} (x) = tan^{2} (x)
