Find the values of $sin$, $cos$, and $ an$ for $45^circ$.
Answer 1
Ella Lewis
To find the values of $\sin$, $\cos$, and $\tan$ for $45^\circ$, we use the unit circle.
For $45^\circ$:
$\sin 45^\circ = \frac{\sqrt{2}}{2}$
$\cos 45^\circ = \frac{\sqrt{2}}{2}$
$\tan 45^\circ = 1$
Thus,
$\sin 45^\circ = \frac{\sqrt{2}}{2}$
$\cos 45^\circ = \frac{\sqrt{2}}{2}$
$\tan 45^\circ = 1$
Answer 2
Henry Green
Using the unit circle, we can determine the values for $sin 45^circ$, $cos 45^circ$, and $ an 45^circ$.
At $45^circ$:
$sin 45^circ = frac{1}{sqrt{2}} = frac{sqrt{2}}{2}$
$cos 45^circ = frac{1}{sqrt{2}} = frac{sqrt{2}}{2}$
$ an 45^circ = frac{sin 45^circ}{cos 45^circ} = 1$
Answer 3
Matthew Carter
For $45^circ$ on the unit circle:
$sin 45^circ = frac{sqrt{2}}{2}$
$cos 45^circ = frac{sqrt{2}}{2}$
$ an 45^circ = 1$
