How to use trigonometry on calculator

[bcalkins]

I know this is a pretty basic question, but it's holding me back from doing my homework due tonight. How do I use trig functions on my calculator. For example and problem in my book says:
(483 N) cos (44) = 347 N
When I plug it in my calculator like so:
(483)cos(44) =
I get: 482.9243181

What am I doing wrong??
Thank you SO much!

Your calculator is finding the cosine of 44 radians; You want to find the cosine of 44 degrees. If you have a T.I. 85 or 86, here's how to change the calculator from degrees to radian mode:

Press MODE.
The third option changes the angle mode between degrees and radians. Set this to degrees.
