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
(easy to remember, 360deg in a circle, 2pi radians in a circle)

Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.
The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.
But to compute trig functions
You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.
MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).

SOURCE: How do I find inverse
First, make sure the calculator is set to degrees (2nd [FORMAT] down-arrow).
Put in the value, press INV, the appropriate function key, and =.
For example, to find the inverse sine of .3, press
. 3 INV [SIN] =

SOURCE: it is giving the wrong
Make sure you have the proper angular mode set. Press MODE to bring up the mode screen. Use the arrow keys to highlight either Radian or Degree on the third line and press ENTER. Press 2ND [QUIT] to exit the mode screen.
