Typing integrate(sin(x),x) in the workbook gives the correct answer -cos(x)
In the shell I get
 
sage: integrate(sin(x),x)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

I get this error in binary downloads sage-6.2, sage-6.3 and in self compiled sage-6.3.

It works well for me (compiled from sources). Could you give more details about your distribution's version, the binary build you used, etc?

I downgraded because important information was missing.

@rws: Please do not downvote questions, especially those from newbies. While I agree that the question lacks the most important detail, we should be a welcoming community. Asking for this information as @tmonteil has rightly done is the way. If we get no response after a couple of months, we could close the question as being too localised.

Try to reset Sage by typing reset(), then try the command again.
