I know this would be extremely difficult, but the only available alternative for the mobile ( PocketCAS) performs indefinite integration in an awkard, unreliable manner... it'd be great if SMath could do it. I guess this one is a quite a long way off though

Sorry to revive an old thread. I am looking to do indefinite integration (mostly use the portable version) and all I can find is the definite in the tool bar. Did I miss anything? Trying to solve a problem and the derivative of ln(x)=1/x, but I can not integrate 1/x to get ln(x) with SMath

Trying to solve a problem and the derivative of ln(x)=1/x, but I can not integrate 1/x to get ln(x) with SMath for a indefinite integral type only the first and 2nd arguments for the int() function. Example: int(1/x,x) This produce a indefinite integral. If you type the 3rd and 4th arguments, you have the limits of integral. Regards, Oscar

Oscar,
although int(1/x,x) displays correctly, it does not symbolically solve. Try it. It graphocally shows the integral with 1/x not the result. am I doing something wrong?

ElSid,
Symbolic integration is not yet implemented in SMath.
