sin(20x)=0

sin (20 x) = 0

x = \frac{πn}{10}, x = \frac{π}{20} + \frac{πn}{10}

Solution steps

sin (20 x) = 0

General solutions for

sin (20 x) = 0

20 x = 0 + 2 πn, 20 x = π + 2 πn

Solve

20 x = 0 + 2 πn : x = \frac{πn}{10}

Solve

20 x = π + 2 πn : x = \frac{π}{20} + \frac{πn}{10}

x = \frac{πn}{10}, x = \frac{π}{20} + \frac{πn}{10}

sin (8 x) + sin (4 x) - 0.5 sin (6 x) = 0

4 sin^{2} (θ) + 4 cos (θ) = 0

cos^{2} (x) = \frac{( 8 k - 9 )}{9}

sin (x) + cot (x) cos (x) = 3

4 sin^{4} (x) + 3 sin^{2} (x) - 1 = 0
