Find the values of $ sin $, $ cos $, and $ an $ for $ 45^{circ} $ using the unit circle.

To find the values of $ \sin $, $ \cos $, and $ \tan $ for $ 45^{\circ} $ using the unit circle, we start with:

\n

\n

• $ \sin(45^{\circ}) = \frac{\sqrt{2}}{2} $

\n

• $ \cos(45^{\circ}) = \frac{\sqrt{2}}{2} $

\n

• $ \tan(45^{\circ}) = 1 $

\n

Using the unit circle, the values for $ 45^{circ} $ are:

$ sin(45^{circ}) = frac{sqrt{2}}{2} $

$ cos(45^{circ}) = frac{sqrt{2}}{2} $

$ an(45^{circ}) = 1 $

For $ 45^{circ} $:

$ sin(45^{circ}) = frac{sqrt{2}}{2} $

$ cos(45^{circ}) = frac{sqrt{2}}{2} $

$ an(45^{circ}) = 1 $
