30cos(30x)+14=-16

30 cos (30 x) + 14 = - 16

x = \frac{π}{30} + \frac{πn}{15}

Solution steps

30 cos (30 x) + 14 = - 16

Move

14

to the right side

30 cos (30 x) = - 30

Divide both sides by

30

cos (30 x) = - 1

General solutions for

cos (30 x) = - 1

30 x = π + 2 πn

Solve

30 x = π + 2 πn : x = \frac{π}{30} + \frac{πn}{15}

x = \frac{π}{30} + \frac{πn}{15}

x, cot (- x) cos (- x) + sin (- x) = - \frac{1}{f}

cos (x) = - \frac{2}{3}

10 cos^{2} (x) + 5 cos (x) - 5 = 0

2 sin (x) = - 3

3 sec (θ) - 2 = 0
