## What to assume...

Hello. The reason why maple's give the output you state, is that you need to give maple more information about the variables. If you want to know why maple has this problem, please set the global variable: _EnvAllSolutions:=true: Your Maple input would then look like this: >restart:_EnvAllSolutions:=true: >int(1/3*(-6*u2^2+u2*(3*z+9*u3)+z^2-5*z*u3-2*u3^2)*(z-u3)*(z-u2)/(u2-u3)^4, u3 = z .. 1); The output will be long, but it will be the complete answer depending wheter the variable, u2 is between z and 1. If you want to use assumptions insted, you can for example (if this is correct): int(1/3*(-6*u2^2+u2*(3*z+9*u3)+z^2-5*z*u3-2*u3^2)*(z-u3)*(z-u2)/(u2-u3)^4, u3 = z .. 1) assuming u2>1,z<1 Hope this helps? //Sentinox

## Command option...

Thank for your prompt reply. Could you please explain the option: >norm(U,2); What does the 2 mean, and why is used 2 (why not one or 3?) TIA //Sentinox
