A user wondered why an example of integration by parts from the Calculus Study Guide was immediately showing the final answer instead of the parts steps shown in the Guide. 

We suggest users pay special attention to the "Initialize" rows of the Guide example(s) where converting the integral to inert form is discussed. 

Using an inert form of the integral ensures that Maple does not evaluate the integral unexpectedly. 


Int(exp(a*x)*cos(b*x), x)


Parts(Q, exp(a*x)) = sin(b*x)*exp(a*x)/b-(Int(sin(b*x)*a*exp(a*x)/b, x))
