SOURCE: graphing trig functions
Put the calculator in radian mode and it will graph trig functions just fine. If you don't know how to change it to radians, then go to mode and cursor over to select radians. I am assuming you know where the sine, cosine, tangent, etc. keys are.

SOURCE: wrong trig ratio
Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.

SOURCE: Using Tan,sin, cosin
Alot of people seem to be having this problem. Angles can be measured in two units, degrees and radians. Your calculator is currently doing everything in terms of radians. I have an 84 but I'm sure the 83 is similar, go under MODE and look for Degrees and Radians and make sure you choose degrees. if you have to convert 360[degrees] = 2* pi [radians]
(easy to remember, 360deg in a circle, 2pi radians in a circle)

This means that you are using a non-algebraic variable in an expression. I know, I am not even paraphrasing. Exemple: if you write 2 + johnQ, where johnQ is a table of data, a picture or a GDB, graphical data base object.
Here is an exemple where mat is a 2X2 matrix and mot is a table.
Hope it helps.
