Question

What are two values of `theta` that satisfy `sintheta=-0.1392`?

Answer 1

`188^@; 352^@`

Explanation:

Calculator gives:
sin x = -0.1392 --> x = - 8^@00, or (360 - 8) = `352^@`
Trig unit circle gives another arc x that has the same sin value:
x = 180 - (-8) = 188^@
Answers for (0, 2pi):
`188^@; 352^@`
