Maple gives plot inconsistent with equation

[graupner1000]

Hi,

OK, its night, I've been in front of this computer for eight hours and am slowly but surely going insane, not least because of the latest in a series of issues in what, I was hoping, would be a straightforward calculation.

So here it goes:

Basically I'm using Maple to conduct what would otherwise be a rather lengthy and not at all pretty calculation. This is supposed to end with determining the imaginary part of the resulting function which will, providing all goes well, be equal to 0. And, using simplify(evalc(Im(f(t))), where f(t) is the function I have spent the weekend finding, this is indeed the case. HOWEVER, when I now go to plot the imaginary part using plot(Im(f(t))), I get a graph that looks like an ekg during a cardiac arrest (that is to say it isn't showing anything that lokes like a function that equals zero).

So now the obvious question: WHY?

Also its probably worth mentioning that in order to get zero it is necessary to use simplify(evalc(Im(f(t))) and just evalc(Im(f(t)) which gives an answer that is not zero.

I have uploaded I picture of the graph and some screenshots of the function I am using(like I said, it isn't pretty).

I would really appreciate some input and be eternal grateful for any kind of help.

Thank you for reaching out for help with your calculation issue. I can understand the frustration and exhaustion that comes with spending hours in front of a computer trying to solve a problem. I would like to offer some suggestions that may help you with your current situation.

Firstly, it is important to make sure that your calculations are accurate and error-free. Double check your inputs and equations to ensure that there are no mistakes. Sometimes even a small typo can cause a major issue in the final result.

Secondly, when plotting a function, it is important to specify the range of values for the independent variable. Make sure that the range you have chosen is appropriate for the function you are trying to plot. It is also helpful to use different colors or styles for the real and imaginary parts of the function to clearly distinguish them in the graph.

Thirdly, it is possible that there may be a bug in the software you are using. I would suggest checking for updates or trying a different software to see if you get the same result. It may also be helpful to consult with other experts in the field or reach out to the Maple support team for assistance.

Lastly, it is important to keep a clear and organized record of your calculations. This will not only help you in identifying any mistakes but also serve as a reference for future calculations.

In conclusion, I hope these suggestions will help you in resolving your issue. Remember to take breaks and rest your mind when needed. Good luck with your calculation and don't hesitate to reach out for help if needed. Keep up the good work!
