Sounds like you may have variable set which is being applied to each function. A reset will not clear this. Check your sw version(be specific) and download the exact patch from the manufacturer.

The default variable in parametric functions must be called t. You can enter the limits you want. However if you type in 2 Pi it will be converted on the entry line to 6.28. The default tstep is 0.13 which is about pi/24. I fail to see what the commotion is about. In this representation of the witch of Agnesi, the variable t is between 0 and 4Pi, and the step tstep is 0.13, a little less that pi/24 Reset your calculator and restart
