Question 200357: Hi all, im not sure whether this is really a proper question. But I need to know if there is a correct manaula method with full working to do the following. I normally do them on calculator but want to know if I should be showing working.
For the following: Find all angles between 0 and 360 which satisfy's the equations sin theta = 0.5
I have several otehr along the same lines an just wanna make sure im not doing them incorrectly.
Thanks, -Nick.

You can put this solution on YOUR website!
sin theta = .500
.
arc sin theta = 30 degrees
.
check sin 30 = .500,,,,,,ok
.
Now there is another answer,,,,,,working off the ref line at 180 deg
.
180-30 =150 deg
.
check sin 150 = .500,,,,,ok
