I am a new user of Maple (Dec 2014). I am trying to calculate an integral related
to mechanical loss. Temperature is a variable in the problem (as is time), and if
I use a sinusoidal (sine or cosine) temperature-time relationship, I think all works fine.
A difficulty is that the experiments have two-hour hold times(i.e., 7200 seconds) (followed by 22 hours of sinusoidal temperature variation.)
The experiments run for several weeks or months.
I tried using Heaviside functions to model the hold times.(Constant temperature periods)
Now I am receiving errors such as " Error, (in tools/eval_foo/do) too many levels of recursion..."
Probably the Maple code is crude and/or sloppy. Most of the code is simply the setting of constants in the problem.
I will be grateful for suggestions and comments--the file is attached. Thank you. John B
