Finding Maximum Positive and Negative Value of a Function (Moments)

[CWEngineer]

I have a function M(x) which is the moments. Do you guys know how can I determine the maximum negative and positive moment value from this function. Thanks

differentiate it and find the zeros (using, say, the root function or a solve block). It may be prudent to plot it first to determine the existence and neighbourhood of any zeros.

Do you know if there is a predefine function in Mathcad that would determine the max. Pos and max neg. moment?

There isn't. You've got to work it out, but it should be straightforward (caveated by not seeing your M(x)).
