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.

Hello people in mapleprimes,

Please help me with simplifying the next expression.
This e1 has the expression of ((epsilon-1)*k/epsilon)^epsilon in the numerator and the denominator. How can I collect each of them with that expression?

e1.mw

Thanks in advance.

Hello people in mapleprimes,

I am using maple 2016's standard UI.
And, I write save command in the ending place there.

And, while I write a code, whenever I think I had better put a name of an expression on a list in another .mpl file, to refer it later, I scroll down the cursor to the ending of the worksheet, and write the name of the expression, and again I bring the cursor back to the place where I wrote an expression whose name I wrote among the arguments of save.
  But, this is a little inconvenient. I have to find the original place where I had been before I moved to the end of the worksheet. But, on the other hand, using a bookmark seems complicated. Isn't there any better way to go to the place of the save command, which is the end of the worksheet, and to go back to the original place soon.

I hope you will give any hint to me. Thanks in advance.

 

Hello people in mapleprimes,

I want to modify the following expression a to b. For it, I used c code.
But, as seen in d, just using c returns a. Originally, I intended phi being between 0 and 1, so
that 1-phi >0. Isn't any better way to modify a to b? and it is better to have maple sort expression remembering 1-phi to be positive, and to have maple give any priority to it in modifying a to b.

a:=(-2*theta+1)*phi/(phi-1)+theta;
b:=(2*theta-1)*phi/(-phi+1)+theta;
c:=simplify(-1*numer(op(1,aa)))/simplify((-1)*denom(op(1,aa)))+theta;
d:=simplify(c)
(-2*theta+1)*phi/(phi-1) + theta

I will be very glad if you borrow me your idea.

Thank you in advance.

I read a code of remove(t->t=".", b);
t->t="." is a Boolean-valued procedure.

But, then, why does (t->t=".")(9); not return false like (t->t^2)(3); returns 9?
How can I have maple return false?

Thanks in advance.

Hello people in mapleprimes,

I have an expression, which apparently can be factored with (beta-1)

e1 := -(beta-1)*L*s*lambda*Omega^3+(beta-1)*L*s*g^k*epsilon*(T*lambda-T+1)*Omega^2+(beta-1)*L*s*(T+lambda-1)*Omega-(beta-1)*L*s*g^k*T*epsilon*lambda;

I want this expresson factored with (beta-1) but keeping other terms the same as

e2:=-L*s*lambda*Omega^3+L*s*g^k*epsilon*(T*lambda-T+1)*Omega^2+L*s*(T+lambda-1)*Omega-L*s*g^k*T*epsilon*lambda;

Is this possible?

I hope you will help me for this.

Thanks in advance.
