We have the trigonometric equation:
We need to solve for
. First, we solve for
(subtract 3 from both sides)
(divide both sides by 2)
So we are looking for angles
with a sine of
. If you draw a unit circle and measure your angle counterclockwise from the positive x-axis, such an angle will be below the x-axis (since the sine is negative) and make a 30 degree (or
radian) angle with the x-axis (since
). There are two such angles between
are your two solutions.
