Question

question
find the reference angle for a rotation of \frac{3\pi}{10}.
answer
attempt 1 out of 3

Explanation:

Step1: Determine the quadrant

Since \(0<\frac{3\pi}{10}<\frac{\pi}{2}\), \(\frac{3\pi}{10}\) is in the first quadrant.

Step2: Recall the reference - angle formula

For an angle \(\theta\) in the first quadrant (\(0 < \theta<\frac{\pi}{2}\)), the reference angle \(\theta_{r}=\theta\).

Answer:

\(\frac{3\pi}{10}\)
