## Incorrect definite integration of hyperbolic funct...

Hi Guys,

I am trying to intgrate a function involving hyperbolic functions in a range of 0 to 1 and it is giving me very large value of 10^94. However, on doing integration terms terms i can see that some large terms involving 10^191 cancel out with each other and I can have a fnite value of this integration. It would be really helpful if someone can help me out why it is happening with int function and how can I solve this case involving hyperbolic function. For reference maple file is attached. Thanks in advance and much appreciated.

## How to simplify multiple definite integrals...

Hi Guys,

I need help regarding simplifying definite integrals. I have following expression

As we can notice the limit for each integral is same, so I should be able to take these integral limit outside. I am trying to use collect and simplify, but both of these command are not working. It would be really helpful for me if I can get the solution for it.

Please find the attached example sheet also.example.mw

## How to use factor elementwise?...

Hi Guys,

It might be a very basic question, but I am struggling with it for a quite a time.  I have an expression in a form of

f(x)=h(x)+g(x);

and I want to use factor operation elementwise, i.e., it can individually act on h(x) and can give me

f(x)=h1(x)*h2(x)+g1(x)*g2(x). But whenever I am putting factor operation with elementwise it is not giving me desired answer. It would be really helpful and great if someone can help me out.

I am attaching maple sheet for reference also.

## Solving a Quadratic Diophantine Equation with 3 va...

How do I find integer solutions to this non-linear equation:

8= 7(x^2+y^2+z^2)+2x+4y-8z.

Tried isolve and it wasn't working. (I guess too many variables?)

Also, if f(x,y,z) is the RHS, how do I write a loop that finds integer solutions to f(x,y,z)=c for |x|,|y|,|z|< N, say?

## How to display each vector turn on the same axis o...

How do I draw three vectors on the same axis of coordinates, I see this vector appear after the previous vector one second  and on the screen when this vector appears, the previous vector remains on the screen and on the last screen I see all three vectors with the Maple command?

Example : plottools :- arrow( [1, -2], [4, -1], 0.001, 0.05, 0.1), plottools :- arrow( [-1, 3], [2, 1], 0.001, 0.05, 0.1), plottools :- arrow( [0, 2], [-3, 0], 0.001, 0.05, 0.1).

Thanks so much for the help of everyone!

## How to transform a function plot by "shifting" hor...

Hello,

I will explain my problem on a simple function and some data.

```mg:=78.54*7.85*1e-9*1000*9.81;l:=10000;l0:=12000;h:=0;H := 28.399;
eta:=mg*l/(2*H);
zeta:=arcsinh(mg*h/(2*H*sinh(eta)))-eta;
z:=H/mg*(cosh(mg/H*x+zeta)-cosh(zeta));
plot(z,x=0..l);
```

Above is a definition of an initial plot. Now I would like to draw a new plot in which every x coordinate is shifted horizontally by a function:

`deltax:=H*arcsinh(x)-x;`

As you see I can't use translate or scale so I've tried to use a transform function but I can't do it the right way.

I would be grateful for any ideas.

Greetings,

Iza
