# Math Help - Solving Trigonometric equations

1. ## Solving Trigonometric equations

Find the solution of the equation if $0 \leq x \leq 2\pi$
Question

$4sin^2t-1=0$
Attempt:
t=-30/330
t=30/150

Is my attempt correct?

Thank you

2. Hi

$4 \sin^2t - 1 = 0$ can be factored in $(2 \sin t - 1)(2 \sin t + 1) = 0$ which implies $\sin t = \frac12$ or $\sin t = -\frac12$
