Question: integrating with lots of parameters

Hello,

I am having trouble with posing an integration for the following function, wrt z.

u:= sin (theta)  * ((s^2 + z^2)/2 +h*z)

I want to be able to change the values of h, s, and theta.

I would like to integrate u, wrt z, from s to h.

I have tried the basics, such as....

int(u, z)   and

int(u, z=s..h)

I get the integrand symbol and a general setup but I am not posing it clearly enough to get Maple to perform the integration.

Thanks for any help you can offer.

PS:  I am obviously a beginner.  I can perform these calculations by hand considerably quicker than the absurd amount of time I am spending trying to learn Maple, but I am no good to my students if I can't master this software myself.  So to this end, does anyone know a good book, filled with examples and clear explanations, regarding Maple?  I find the help files simplistic and rather cryptic.  I would say, "its Greek to me", but I studied ancient Latin and Greek for 6 years and it makes considerably more sense than the Maple Help files.  Each time I resort to the Help files, I find my blood pressure rising and my IQ dropping.  Any suggestions would be greatly apprecieated.
