-pi/(30)sin(pi/(90)(x+20))=0

- \frac{π}{30} sin (\frac{π}{90} (x + 20)) = 0

x = 180 n - 20, x = 180 n + 70

Solution steps

- \frac{π}{30} sin (\frac{π}{90} (x + 20)) = 0

Multiply both sides by

30

- π sin (\frac{π}{90} (x + 20)) = 0

Divide both sides by

- π

sin (\frac{π}{90} (x + 20)) = 0

General solutions for

sin (\frac{π}{90} (x + 20)) = 0

\frac{π}{90} (x + 20) = 0 + 2 πn, \frac{π}{90} (x + 20) = π + 2 πn

Solve

\frac{π}{90} (x + 20) = 0 + 2 πn : x = 180 n - 20

Solve

\frac{π}{90} (x + 20) = π + 2 πn : x = 180 n + 70

x = 180 n - 20, x = 180 n + 70

sin (2 x) = - \frac{1}{2}

cos (x) = - \frac{22}{7.28 \cdot 20}

sec^{2} (x) = 4 tan (x)

x, 1 + sin (2 x - 3 0^{\circ}) = 0

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