I know the following is WRONG. But I'm trying to layout my method, to know where am I messing up.

I'm converting theta to be degrees, since it is easier for me.

-1.8 * 180 = -324

Angle coterminal to -324 = 36

Reference angle = 90 - 36

^- This is definitely wrong but I can't think of any other methods.

Your angle is in quadrant IV so the reference angle of +324 would be 360 - 324 = 36.

Also, did you remember to convert back to radians?

Please forget about ever using degrees.

Take a look at this webpage.

Because the reference angle is .
