How many solutions does the equation sin(4x)= 3/4?

MAVERICK [17]

$sin(4x)= \dfrac{3}{4}$

$4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4})$

<span>Since sin is a periodic function, add the periodicity.
</span>
$4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

$

$4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ$

$x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

$x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$
