-900cos(30x)=0

- 900 cos (30 x) = 0

x = \frac{π}{60} + \frac{πn}{15}, x = \frac{π}{20} + \frac{πn}{15}

Solution steps

- 900 cos (30 x) = 0

Divide both sides by

- 900

cos (30 x) = 0

General solutions for

cos (30 x) = 0

30 x = \frac{π}{2} + 2 πn, 30 x = \frac{3 π}{2} + 2 πn

Solve

30 x = \frac{π}{2} + 2 πn : x = \frac{π}{60} + \frac{πn}{15}

Solve

30 x = \frac{3 π}{2} + 2 πn : x = \frac{π}{20} + \frac{πn}{15}

x = \frac{π}{60} + \frac{πn}{15}, x = \frac{π}{20} + \frac{πn}{15}

sin^{2} (x) = \frac{( 9 m - 9 )}{7}

sin (x) = 0.55669

6 sin (2 x) = 0

(100 \cdot 9.8 \cdot l (1 - cos (θ))) = 0.018

2 sin (x) - sin (2 x) = sin (x)
