Pasos de solución

sin (\frac{5 x}{2}) \leq 0.6

Para

sin (x) \leq a

, si

- 1 < a < 1

entonces

- π - arcsin (a) + 2 πn \leq x \leq arcsin (a) + 2 πn

- π - arcsin (0.6) + 2 πn \leq \frac{5 x}{2} \leq arcsin (0.6) + 2 πn

Pi

a \leq u \leq b

entonces

a \leq u and u \leq b

- π - arcsin (0.6) + 2 πn \leq \frac{5 x}{2} and \frac{5 x}{2} \leq arcsin (0.6) + 2 πn

- π - arcsin (0.6) + 2 πn \leq \frac{5 x}{2} : x \geq \frac{- 2 π - 2 arcsin ( 0.6 )}{5} + \frac{4 π}{5} n

- π - arcsin (0.6) + 2 πn \leq \frac{5 x}{2}
