Answer:
\((-1,0)\)
Step-by-step explanation:
we know that
In the unit circle
The point \((1,0)\) correspond to \(0\)
The point \((0,1)\) correspond to \(\pi/2\) or \(-3\pi/2\)
The point \((-1,0)\) correspond to \(\pi\) or \(-\pi\)
The point \((0,-1)\) correspond to \(3\pi/2\) or \(-\pi/2\)
therefore
\(-\pi\) -----> correspond to the point \((-1,0)\)
