I am trying to get my problem to print more efficiently, I have tried the vpa tool, and it works nicely, but I have no customization (as far as im aware) as to how to control the number of decimal places on the polynomial that is being printed using these commands while having a symbolic function/polynomial.
How can I tidy up this so that it prints in an easier to read format, with, for example, 5 decimal places rather than the amount it has?

producing:
