Find the angle in degrees for which the $sin$ and $cos$ values are equal on the unit circle.
Answer 1
To find the angle $\theta$ in degrees for which $\sin(\theta) = \cos(\theta)$ on the unit circle, start by equating the two trigonometric functions:
$ \sin(\theta) = \cos(\theta) $
Divide both sides by $\cos(\theta)$ (where $\cos(\theta) \neq 0$):
$ \frac{\sin(\theta)}{\cos(\theta)} = 1 $
So, the tangent function is:
$ \tan(\theta) = 1 $
The angle $\theta$ for which $\tan(\theta) = 1$ is:
$ \theta = 45^\circ $
Answer 2
To find the angle $ heta$ where $sin( heta) = cos( heta)$ on the unit circle:
$ sin( heta) = cos( heta) $
Divide both sides by $cos( heta)$:
$ frac{sin( heta)}{cos( heta)} = 1 $
Which implies that:
$ an( heta) = 1 $
The angle $ heta$ must be:
$ heta = 45^circ $
Answer 3
If $sin( heta) = cos( heta)$:
$ an( heta) = 1 $
Then:
$ heta = 45^circ $
