## Yes,...

I had used simplify with the LegendreP.

Your method for the SphericalY conversion looks a little simpler than the other suggestion in this thread. I'll give it a try.

## Thanks, again...

## ??...

I'd just like to get the worksheet output to look a little more 'conventional' .... to a Chemist. That is, I'd like, for example, the output for SphericalY(1,1,phi,theta) to show as a constant times sin(theta).exp(I.phi).

I've tried simplify(testp,trig) without success.

## O. K., now how do I......

Both of your last two suggestions, elementary and arctrig, worked to give me what I expected the function to give ... as, for example, LegendreP does without the convert.

Now, is there any way to get Maple to recognise that sqrt(cos(theta)-1)sqrt(cos(theta)+1)  is i.sin(theta) in the output?

## O.K.; thanks...

I had gathered from the docs that hardware evaluation was somehow involved, but ran into a stone wall at that point. By the way: I suspect, but can't be sure that this is the source of the problem in trying to export the plot as a dxf. That was the subject of a question which I asked about a week ago, and which has had no responses. I have been able to export some other plots. Don Ritchie

I'll give it a try. If I have trouble .... I'll be back. EDIT* Wow !! That worked beautifully. Thanks a million. *END EDIT Don Ritchie

Never would have thought of that !! Don Ritchie

That really helped tremenduously. I'd never have found the allvalue command by myself. Don Ritchie
