Question

At what angle theta does sin(x) equal 1/4 on unit circle?

Answer 1

Find x knowing `sin x = 1/4`

Ans: `14^@48` and `165^@52`

Explanation:

Use calculator:
sin x = 1/4 = 0.25 --> arc `x = 14^@48.`
Trig unit circle gives another arc x that has the same sin value -->
`x = 180 - 14.48 = 165^@52`
