0=-1/7 cos(7t)

0 = - \frac{1}{7} cos (7 t)

t = \frac{π}{14} + \frac{2 πn}{7}, t = \frac{3 π}{14} + \frac{2 πn}{7}

Solution steps

0 = - \frac{1}{7} cos (7 t)

Switch sides

- \frac{1}{7} cos (7 t) = 0

Multiply both sides by

- 7

cos (7 t) = 0

General solutions for

cos (7 t) = 0

7 t = \frac{π}{2} + 2 πn, 7 t = \frac{3 π}{2} + 2 πn

Solve

7 t = \frac{π}{2} + 2 πn : t = \frac{π}{14} + \frac{2 πn}{7}

Solve

7 t = \frac{3 π}{2} + 2 πn : t = \frac{3 π}{14} + \frac{2 πn}{7}

t = \frac{π}{14} + \frac{2 πn}{7}, t = \frac{3 π}{14} + \frac{2 πn}{7}

cos (α) = \frac{5}{13}

tan (x) = 3, 0 \leq x \leq 2 π

3 sec (θ) + 7 = 0

(tan (x) + 1) (sec (x) - 1) = 0

cos (θ) = 23
