I am working with quite complicated (i.e., numerous) trigonometric functions. Let’s say one equation does not fit on an A4 sheet of paper. Rewriting the expressions by hand would be extremly tedious, but thanks to computer algebra systems, I managed to do a symbolic computation and arrive at something like f (0) = 1 (for the sake of the example) as a final and main result.
How can I explain such a thing in a scientific journal (in mechanics)?
A few possibilities, that I considered:
The calculations yield f (0) = 1
But I feel guilty because I did not make the calculation by myself.
Using ComputerProgram++, we showed that f (0) = 1.
But should I provide the code in this case?
