Determine the sine value at an angle of $ frac{pi}{4} $ on the unit circle
Answer 1
Chloe Evans
To determine the sine value at an angle of $ \frac{\pi}{4} $ on the unit circle, recall that at this angle, the coordinates are:
$ ( \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} ) $
The sine value corresponds to the y-coordinate:
$ \sin( \frac{\pi}{4} ) = \frac{\sqrt{2}}{2} $
Answer 2
Ella Lewis
To find the sine value at $ frac{pi}{4} $ on the unit circle, note that the coordinates at this angle are:
$ ( frac{sqrt{2}}{2}, frac{sqrt{2}}{2} ) $
Thus, the sine value is:
$ sin( frac{pi}{4} ) = frac{sqrt{2}}{2} $
Answer 3
William King
At an angle of $ frac{pi}{4} $, the sine value is:
$ sin( frac{pi}{4} ) = frac{sqrt{2}}{2} $
