Question

5 sin^2 x = sin x please help.

Answer 1

$\\ \sf\longmapsto 5sin^2x=sinx$

• Divide both sides by sin x

$\\ \sf\longmapsto \dfrac{5sin^2x}{sinx}=\dfrac{sinx}{sinx}$

$\\ \sf\longmapsto 5sinx=1$

$\\ \sf\longmapsto sinx=\dfrac{1}{5}$

$\\ \sf\longmapsto sinx=0.2$

$\\ \sf\longmapsto x=sin^{-1}(0.2)$

$\\ \sf\longmapsto x=11.53$
