Question

How do you solve `sin(theta)= 0.4` over the interval 0 to 2pi?

Answer 1

`23^@58 and 156^`42 for (0, 360)#

Explanation:

Use calculator:
sin x = 0.4 --> arc `x = 23^@58`
Trig unit circle gives another arc x that has the same sin value:
`x = 180 - 23.58 = 156^@42`
Answers for (0, 360)
`23^@58, 156^@42`
