Hello, I have been using mathcad for a only a few weeks, so my knowledge of it is limited.

I have a set of data points which I have created some polynomial and cubic splines on a graph.

What I want to do is calculate the slopes and change in slope of the curves.

Any help on a mathcad function that can do this would be appreciated, I was hoping I could attach my mathcad work sheet but won't let me attach the file :(

Thanks in advance :cool:
