Draw the graph and a line at `y=-0.4321`

The line cuts the graph twice in the range, so there are two solutions.

The solutions are in the bottom right quadrant.

The reference angle is the solution in the range `-90 <theta < 90`

and is the solution to `sin^(-1)(-0.4321) = -26 ^@`

The solutions are of the form `180n - 26`,`n` even and `180n +26`, `n`odd

ie, `theta =` `-386^@, -154^@, -26^@, 206^@, 334^@` etc

**There are two solution in 0<theta<360**

**The solutions are in the bottom right quadrant**

**The reference angle is in the range [-90,90] and is -26
degrees**

**theta = -386, -154, -26, 206, 334 etc**
