sin^2(x/2)=0

sin^{2} (\frac{x}{2}) = 0

x = 4 πn, x = 2 π + 4 πn

Solution steps

sin^{2} (\frac{x}{2}) = 0

Apply rule

x^{n} = 0 \Rightarrow x = 0

sin (\frac{x}{2}) = 0

General solutions for

sin (\frac{x}{2}) = 0

\frac{x}{2} = 0 + 2 πn, \frac{x}{2} = π + 2 πn

Solve

\frac{x}{2} = 0 + 2 πn : x = 4 πn

Solve

\frac{x}{2} = π + 2 πn : x = 2 π + 4 πn

x = 4 πn, x = 2 π + 4 πn

tan (t) = 2

- 120 = - 90 - arctan (0.1) + arctan (0.1 x)

3 tan (x) = 0

2 sin^{2} (x) - 15 sin (x) + 7 = 0

x, cos (x) = \frac{- 3}{5}
