Question

What is the solution of 5sin2θ=3 for 0≤θ≤2π? Please help.

Answer 1

Answer:

C) $\theta\approx\{0.3218,1.249,3.463,4.3908\}$

Step-by-step explanation:

$5\sin2\theta=3;\: 0\leq\theta\leq 2\pi\\\\\sin2\theta=\frac{3}{5}\\ \\2\theta\approx\{0.6436,2.498,6.926,8.7816\}\\\\\theta\approx\{0.3218,1.249,3.463,4.3908\}$
