## How to rescale axis?...

Maple

Hi all,

I have recentry constructed Fourier amplitude and Fouier Power graphs which are plotted against the frequency of the oscillations, like the picture below.

I would like to change the frequency scale along the x axis into a period scale in order to Fourier analyse future ODE systems in  terms of period rather than frequency.

But I unsure how to manipulate my code to do so.

Any help would be much apreciated, and the Maple file that I am using is attached.

## How to color point plot?...

Maple

Hi all,

I was wondering if it is possible to add a colour gradient to a point plot to represent another perameter in the data.

For example, each point corresponds to a value of 'f' ranging from 0.1 to 1, and I was wondering how to display this by means of a colour gradient.

Thanks,

## Plotting past a singularity...

Maple

Hi,

I'm trying to use Maple to plot a dependence, but Maple says there is a singularity.

Attached is the Maple file I'm using (Equation 2 and the 2 graphs pertaining to it are the problem)

They should look like the attached graph, but since Maple claims it hits unity, it won't plot any further points.

Is there a way to override this to force Maple to plot after reaching a singularity?

Any help or advice would be very much appreciated

Thanks,

## How to plot Fourier transform?...

Maple 18

Hi,

I was wondering how to go about plotting a Fourier Tranform in Maple.

My assignment is to plot a simple harmonic equation as a Fourier transform, depicting amplitude against fequency.

I've been given: x'' + w^2 x = 0

And want to obtain both the f(x) = a0 sin(wt) + b0cos(wt) form, and a graph of the the amplitude (c^2 =a0^2 + b0^2) against frequency.

I know how to do this on paper but not in Maple, so any help with line commands and layout would be very much appreciated.

Thanks
