Maple is to me difficult. The first version I bought was Maple9, and it was more than 15 years ago. But, I couldn't use it, feeling it too difficult. But, three years ago, I thought Maple might be helpful to my study, and since then, I have continued to learn Maple. As I got able to read the Maple help, I think that I could get to use maple better now than before. But, I feel that I am a beginner yet.

## how to do not to have maple simplify wha...

Maple

Dear people being here,

I have a question.

When I wrote as

aa:=(delta[1]*n[1])/(n[f1]*delta[1]);

maple returned as

aa := n[1]/n[f1]

How can I have maple express the original one, aa:=(delta[1]*n[1])/(n[f1]*delta[1]), not what returned to me?

I hope you will answer to my question.

And, thanks in advance.

## differential of integrated expression...

Hello I have a question about how to differentiate integrated equation .

u:=integrate(q(i),i=0..M);

diff(u,q(i));

doesn't return the equation of 1. I want to differentiate u with respect to the q(i) in q(0)....q(M).

But, I can't.

I am very glad if you tell me how to do about this calculation.
