Find the $ sin $, $ cos $, and $ an $ values for the angle $ heta = 45° $ in the unit circle
Answer 1
Ella Lewis
For the angle $ \theta = 45° $ in the unit circle:
The coordinates are $ ( \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2} ) $.
Thus, $ \sin 45° = \frac{\sqrt{2}}{2} $
$ \cos 45° = \frac{\sqrt{2}}{2} $
$ \tan 45° = 1 $
Answer 2
Christopher Garcia
For $ heta = 45° $:
Since the angle is in the first quadrant, the coordinates are $ ( frac{sqrt{2}}{2}, frac{sqrt{2}}{2} ) $.
Therefore, we have:
$ sin 45° = frac{sqrt{2}}{2} $
$ cos 45° = frac{sqrt{2}}{2} $
$ an 45° = frac{frac{sqrt{2}}{2}}{frac{sqrt{2}}{2}} = 1 $
Answer 3
Matthew Carter
For $ heta = 45° $:
The values you need are:
$ sin 45° = frac{sqrt{2}}{2} $
$ cos 45° = frac{sqrt{2}}{2} $
$ an 45° = 1 $
