 |
|
| Can someone help me? I must have done something to my X variable key. When I integrate, differentiate, factor, etc. my ti-89 always returns a numerical solution instead of the desired result with the variable. My Y and Z keys are working fine, which leads me to believe that Imust have done something to override the X-key. Any suggestions as to what I should do to fix this problem? Thanks for your help! |
