Where's the problem or the work ?
X=3 do you need the working out ?
12 is the principal square root , and −12 is considered a real root.
so 12 is not the only solution
Using the unit circle, the coordinates of the terminal point corresponding to is: (-0.5, 0.866).
<h3>What is the unit circle?</h3>
For an angle the unit circle is a circle with radius 1 containing the following set of points: .
In this problem, the angle is of , hence:
- .
- .
Hence the terminal point is:
(-0.5, 0.866).
