Without using a calculator, compute the sine and cosine of \( \frac{7 \pi}{4} \) by using the reference angle. What is the reference angle? radians. In what quadrant is this angle? (answer 1, 2, 3, or 4) \( \sin \left(\frac{7 \pi}{4}\right)= \) \[ \cos \left(\frac{7 \pi}{4}\right)= \] (Type sqrt(2) for \( \sqrt{2} \) and sqrt(3) for \( \sqrt{3} \).) If \( \theta=\frac{-1 \pi}{6} \), then \[ \sin (\theta)= \] \[ \cos (\theta)= \] Give exact values. No decimals allowed! If \( \theta=\frac{4 \pi}{3} \), then \( \sin (\theta)= \) \( \cos (\theta)= \) Give exact values. No decimals allowed! If \( \theta=\frac{7 \pi}{4} \), then \( \sin (\theta)= \) \[ \cos (\theta)= \] Give exact values. No decimals allowed! The reference angle of 216 degrees is degrees. The reference angle of 317 degrees is degrees. The reference angle of \( -122 \) degrees is degrees.
