Homework Equations
The Attempt at a Solution
The way I did it was to turn it into radians by simply doing the math...
5.76 radians
Then, I multiplied that by 57.3 to get degrees.
330 degrees
After that, I double checked it against -30 degrees so that I could use the table.
I didn't have an issue with getting the correct answers. My issue is with the form.
The answers weren't decimals.
Example:
sin = - 0.5000
cos = 0.8660
tan = - 0.5774
They were left in fraction form.
Example:
sin = - 1/2
cos = [itex]\sqrt{3}[/itex]/2
tan = - [itex]\sqrt{3}[/itex]/3
I have a feeling that my exams want me to answer in the fractional form. And, I don't have an idea of how to do that. Please forgive me if it is obvious.
Also, sorry that my LaTex is rather sloppy. Apparently, the board has changed since I've been away.
Thanks in advance for the help. :D
