(Using Maple 13.01) When performing a symbolic complex integration where the integral will have two (or more) distinct values depending on a parameter in the function maple sometimes return the correct indication of branches and for more complicated expressions the integration only gives the result of one branch (not indicating the different possibilities) A trivial example to help explain my question/thought f(z) = 1/(z+2) Path of integration, |z+1|=r, this means that for |r| <> 1 the integral will simply be 2*Pi*i

I stumbled upon some maple:isms when trying to rewrite some rather simple but tedious (and long) expressions in some filter design I'm working on that it is easy enough (but error prone..)  to do by hand.

Let's illustrate with a trivial example. How can I force maple to do roughly the following simplification

If I have a univariate in negative powers , say,  a*x^(-1) + b*x^(-2), maple will expand this expression as

a/x+b/x^2

how can I prevent maple from converting negative powers to explicit division in 1D / 2D - Output, i.e. I want to keep the polynomial displayed as

a*x^(-1) + b*x^(-2)

?

 

 

 

 

What is the best way to create the equivalent of Matlab stem plots in Maple? (i.e. discrete point plots with a vertical line down to the X-axis - usually used to illustrate a discrete sequence)
