I'm just not getting the syntax to call CAS.diff on my function defined as F1(x) in the Function Symbolic View for each of the iterations. I've tried "f := CAS.diff('F1','X');" but to no avail. Do you have ideas on this?Daryl Whitehttps://www.blogger.com/profile/17782699600215539867noreply@blogger.comtag:blogger.com,1999:blog-9169922911599301079.post-38127686725136345862014-04-19T09:33:44.497-07:002014-04-19T09:33:44.497-07:00Thanks James!
