I'm having trouble understanding the difference between these two integration commands:
clear; syms y;
On my machine (2019b - Windows) and MATLAB Online, using format short I get:
I often receive odd rational approximations when integrating using pi (note that leaving pi out of the integral fixes the issue). I haven't been able to find an answer as to why this happens. I'm assuming MATLAB computes a decimal answer using pi, cuts the approximation at the 14 or 15th decimal place, then creates a fraction out of the result, but why does this happen some times and not others?
