I want to learn more about ImpulseResponse functions and the ImpulseResponsePlot in Maple.
Could anyone please explain how it works ? I want to start with a simple example ie
a simple transfer function which is very easy to understand.

with(DynamicSystems):
sys1 := TransferFunction(s*(s-1)/((s+2)*(s+4)*(s+6))):
ImpulseResponsePlot(sys1, 2);
 

I want to write  K^(p-1)*L^(-p+1)   as   (K/L)^(p-1)  .

How can this be done with maple command without simply typing it ?
 

I want to find a tagent lines to the below contourlines for a function  U := Q[a]^alpha*Q[b]^(1-alpha); given any

value of Q[a] and Q[b]. I know the slope of such a tagent lines but I dont know the intercept. How can I derive such an equation ?

I have strings like "2009-08-01" as tick marks in a plot. I want them to be displayed vertical... how ?

I want to fill a ComboBox (emb.comb) with data but I dont want to do it manually.

I want to assign a list of 200 values to a ComboBox by using some code...how ?
