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 can I show the expression of the following summation as the output, not 11?



Dear people in this board.

I couldn't solve the following equation.



On the other hand, I could solve


Error message was 

Error, (in solve) a constant is invalid as a variable, gamma

Why does this sort of things happen?

I hope that you will tell me about this.

Tahnk you in advance.






I have to questions. One is the main one, about simplifying fractions.

This is equations.









From now, I will explain. Though as I don't know how to put a maple screen on this board I think I will have you feel some inconvenience, please forgive it.

I want to make jj more simple, dividing both of numerator and denominator of jj, with gamma[2]^2.

But, what I could at best was this. First, taking denominator of jj and deviding it with gamma[2]^2 and expanding it like kk. Second, as the first term among that expression had terms of gamma[2] on both of the numer and denom, I picked out the first term as ll in the above maple commands, and simplified it with option: power, in mm. Thirdly, I rewrote kk as in nn.

and Forthly, I rewrote jj with modification of deviding numerator and denominator with gamma[2]^2, using the result which I could get as I wrote above. oo is that. And the result of oo is what I wanted to get.

But, on the other hand, when i divided denom and numer of jj directly by gamma[2]^2, the result I can get then is not 

good one: the output of pp is not what I wanted to get.

Is there more simple way to do what I did in the above? This is a first question.


And, another is how I can post the screen of maple on this question board?


I hope you will answer my question. I thank all of you who will answer these question in advance.





Dear people being here,

I have a question.

When I wrote as


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.



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



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.

Thanks in advance.
