Find the exact value of $ sin(frac{pi}{4}) $ on the unit circle
Answer 1
Joseph Robinson
To find the exact value of $ \sin(\frac{\pi}{4}) $ on the unit circle, recognize that $ \frac{\pi}{4} $ is 45 degrees. The sine of 45 degrees (or $ \frac{\pi}{4} $) is:
$ \sin(45^\circ) = \sin(\frac{\pi}{4}) = \frac{\sqrt{2}}{2} $
Thus, the exact value is:
$ \sin(\frac{\pi}{4}) = \frac{\sqrt{2}}{2} $
Answer 2
Maria Rodriguez
On the unit circle, the angle $ frac{pi}{4} $ corresponds to 45 degrees. The sine of $ frac{pi}{4} $ is:
$ sin(frac{pi}{4}) = frac{sqrt{2}}{2} $
Answer 3
Thomas Walker
The angle $ frac{pi}{4} $ has a sine value of:
$ sin(frac{pi}{4}) = frac{sqrt{2}}{2} $
