I don't understand how to get the sin of .5. My instructor says that the sin of .5 is 30 but I am not coming up with that. I am very frustrated!

Hi I hear you frustration :)
It is the other way around
sin of 30 degrees is 0.5
If you want to go backwards. You have the answer 0.5 and you want to know sin of what =0.5 then you have to use
Inverse sin 0.5 = 30degrees displayed as \(sin^{-1}(0.5)=30^\circ \)
OR arcsin 0.5 = 30degrees displayed as \(asin(0.5)=30^\circ\)
So on this calc (and most other calcs) you press [2nd] [sin^-1]0.5 =
on this calc you can also just type in asin(0.5)=
Some calcs need the brackets others don't
BUT
Make sure you calculator is set to degrees.
On the web2 calc there is a angle toggle at the bottom so you can set it to degrees or radians :)
