Hi everyone,
I have an equation that I would like to let Mathcad simplify for me. It looks like this:
ok 🙂 I know I could simplify it myself, but please consider this an example!
If I select the left side and then Symbolics > Simplify I obtain the highly unsatisfying result:
what I would like is that pi remains expressed as pi!
I have tried, remembering another thread, the "symbolic undefine" pi:=pi (above the equation) but apparently it does not work!
Am I asking Mathcad 15 too much?
thanks for any suggestion!
Best regards, Claudio
PS: no, I do not use Prime 😉
PS2: the equation is derived with some manipulation from ASME Boiler and Pressure Vessel Code, Section III, and is related to the allowable stress in a pipe product, under known inner pressure and external moments, at design condition.
Solved! Go to Solution.
Hi Claudio,
Please upload your Mathcad worksheet.
Try replacing the 1.5 by 3/2
Hey, thanks @AlanStevens it works! I do not understand why, but it works 🙂
I also had the thought with fractions and also tried "Format > Result > Fraction" but it gave ugly fractional approximations of the numbers shown above!
It works because the symbolic engine has a nasty "feature". Whenever it encounters a decimal point it switches to some kind of float/approximation mode (similar to what you achieve if you add "float,20".
