Spreadsheets are not supposed to do symbolic math. There are many CAS[^] available, however.

On a side note: do you really need a tool to compute a symbolic derivative? Big Grin | :-D

Not for my job, but I am starting another degree in October.
Part of the course is Hard Sums.
("Investigative and Mathematical Skill in Science" followed by "Essential Mathematics" then "Mathematical Methods")

I will need as much assistance as possible as I am attempting 90 Credits in the first year, quite a lot for a part time course.

Actually I was suggesting you could do it yourself (without using tools, you know, just pencil & paper...).

Not the plotting, it would have taken too long without the assistance of people like you pointing me to the right place!

It indeed appears that Excel cannot produce derivatives! I poured crude oil all over my keyboard and didn't get petrol. Excel team should fix this immediately.

Solution to your problem:
1) Enlarge target above
2) Print out enlarged image
3) Lay on solid flat surface
4) Bang head on target
5) Repeat step 4 until problem solved.

Dave, that is EXACTLY what I need.

I see that it is a workaround, and that Excel has no Calculus functions per se, so it at least can be done for plotting.
The derivatives are easy enough, mental arithmetic really, but it would have been nice just to pump in a function and have it all done for me.
