Hello all
I want to integrate an equation involving different terms (some of them involve derivatives) the following picture shows the expression and the end result. I can do it manually by multiplying both sides with u'. but how can acheive that in maple
Picture

 

> 

Eq4 := diff(u(xi), xi, xi) = a[0]+a[1]*u(xi)+a[2]*u(xi)^2; Eq5 := int(Eq4, xi); simplify(%)

diff(diff(u(xi), xi), xi) = a[0]+a[1]*u(xi)+a[2]*u(xi)^2

  

Error, (in int) wrong number (or type) of arguments: wrong type of integrand passed to indefinite integration.

  

diff(diff(u(xi), xi), xi) = a[0]+a[1]*u(xi)+a[2]*u(xi)^2
