Question

Solve the equations below exactly. Give your answers in radians, and find all

Answer 1

Answer:

See below (along with unit circle attached)

Step-by-step explanation:

$sin(t)=-\frac{\sqrt{3}}{2}$

$t=\frac{4\pi}{3},\frac{5\pi}{3}$

$cos(t)=\frac{1}{2}$

$t=\frac{\pi}{3},\frac{5\pi}{3}$

It really helps to use the unit circle! I've attached it below for your convenience. Keep in mind that a point on the unit circle is defined by $(cos(\theta),sin(\theta))$ where $\theta$ is measured in radians.
