Find the coordinates of $ frac{3pi}{4} $ on the unit circle
Answer 1
Thomas Walker
To find the coordinates of $ \frac{3\pi}{4} $ on the unit circle, we use the unit circle properties:
The x-coordinate is:
$ x = \cos\left( \frac{3\pi}{4} \right) = -\frac{\sqrt{2}}{2} $
The y-coordinate is:
$ y = \sin\left( \frac{3\pi}{4} \right) = \frac{\sqrt{2}}{2} $
So, the coordinates are $ \left( -\frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} \right) $
Answer 2
Samuel Scott
The coordinates of $ frac{3pi}{4} $ on the unit circle can be found using the unit circle properties:
For the x-coordinate:
$ x = cosleft( frac{3pi}{4}
ight) = -frac{sqrt{2}}{2} $
For the y-coordinate:
$ y = sinleft( frac{3pi}{4}
ight) = frac{sqrt{2}}{2} $
Therefore, the coordinates are $ left( -frac{sqrt{2}}{2}, frac{sqrt{2}}{2}
ight) $
