Guys,

I have a integral caluclation to be done to calculate the profile of a tyre. I need to vary two variables namely r and alpha and need to get a graph out finally.

I tried varying "r" alone , and the equation was working perfect. But woth two variabkes varying in tandem , MathCAD isn;t able to calculate the result.

The calculation sheet is attached herewith.

Why would you expect a surface plot to appear on a 2D chart.

Change your definition to d(a,r):=Im(Your Integral)

Press [Ctrl]-2 (Or get a surface plot up some other way.)

Put 'd' in the place holder of the Surface Plot..

Double click the plot and Under [QuickPlotDate] change Range 1 to [43,45] and Range 2 to [209,312].

Of course you may need to change your screen resolution to 16 Bit High Color before loading the Surface Plot. (Very irritating)

Nathan ,

No I need a 2D plot with the equation result varying with "r" . But to ge the equation result , i have 2 sets of data for "Alpha" and "r" respectively whcih I need to substitute in the equation.
