In english:
Hi, my name is Jorge Daniel... i want to ask you why when i add an cp app to my classpad, the classpad dont do some operations correctly, by example integrals.. Well, i hope you can help me.

I told him that he must gave me more detais and he must come here to write them.

The only guess I can make is, before downloading an add-in he updated his OS and maybe reset his modes. If his modes are different (complex vs. real) he'll get different answers.

Ask him to try the integral in both complex and real mode to see if it makes a different. If this isn't it then have him list...

• The OS version
• What add-in he loaded
• What integral isn't working. What is the answer its giving.
• Finally, what are the mode settings on his ClassPad.
