Question

Solve the sinusoidal equation: 5sin(3x)-1=3

Answer 1

Answer:

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$

Step-by-step explanation:

$5sin(3x)-1=3$

$5sin(3x)=4$

$sin(3x)=\frac{4}{5}$

$3x=0.92729521+2\pi n,2.21429743+2\pi n$

$x=0.3090984+\frac{2\pi n}{3},0.73809914+\frac{2\pi n}{3}$
