## Solving inequalities with conditions...

Maple 18

Hello everyone,

I'm struggling to solve inequalities with conditions.

I have this inequality with 4 variables, which I have some conditions. However, I can't implement this conditions to the inequality and solve using the 'solve' command.

Can anybody help me?

## Problems with the "collect" command...

Maple 18

Hello everyone,

I have a function of 5 variables, A, P, N, k. I want to solve and express as a power series of 'k'

w=F*k+G+H/k+...

and gather the coefficients of each power.

However, the result I obtain in my code differs from the analytical value I found. What am I doing wrong?

Thanks!

## Problems with series expansion...

Maple 18

I am trying to expand a multivariable (more specifically 4 variables) function in powers of one of its variables when it goes to infinity.

However, the result I get is always zero, even if I input (or not) values for some of the other variables.

Can anybody help?

P.s.: I want to do the same for the other two functions I defined in the worksheet as well.

## Discontinuities even with "discont=true"...

Maple 12

Hello everyone,

Even using the command "discont=true", some of the functions I plot still present discontinuities, but some of them do not present.

How can I fix this? This one file ilustrates perfectly the problem.

## How to plot multiple functions in one pl...

Maple 12

I want to plot all three "roots" of the polynom I called 'H[i]' for different values of 'V', in the interval k=0.0..1.0, all in the same plot.

How can I do it, both for real and imaginary parts of H[i]?
