Question
Find the exact value of $\sin \theta, \cos \theta,$ and $\tan \theta$ using reference angles.$$\theta=315^{\circ}$$
Step 1
The reference angle is the acute angle that the terminal side of the given angle makes with the x-axis. We can find it by subtracting the given angle from $360^{\circ}$ if the angle is in the fourth quadrant. So, we Show more…
