Radian mode does not work properly
-1E-13 is a very small number. When doing this kind of a problem you can regard 1E-13 as 0.
Remember that pi is an irrational number. It is only estimated on your calculator. I just played around with a TI-83 and found the following answers:
cos(pi/2) = 0
cos(2*pi + pi/2) = 0
cos(4*pi + pi/2) = 1E-13
cos(20*pi + pi/2) = -1E-13
As you know, that correct answer to each of these is 0. The calculator gives non-zero answers because some very small errors are accumulating. There is nothing wrong with your calculator.

Invalid dim
You're trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.
