How do I prevent that maple scrolls through the worksheet and stops at the bottom when I want to execute the  whole worksheet. If i want to execute the whole worksheet I just want to stay at the same place in the worksheet and I also don't want to expand previousily closed sections. I use document mode. Thanks in advance

In Vector Calculus there are excellent commands for finding the normal vector to a curve (PrincipalNormal and TNBFrame) but none for finding the surface normal vector. It is possible to display the surface normal vector using PlotPositionVector's normal option, but this is good for visualization only, and the vector can't be used for further calculations.

Am I missing something, or is this really missing form the package?

Two example problems to be solved:



I wish to enter in the math dot operator but I can't find the way to enter it in the document mod. I also searched the help and did not find a way.


all I want is to enter dot(varphi)




When I type a operation in maple such as limit, derivative, integral... then I enter. It only show the result. but I want it to show clearly  each step of  solving. What should I do?


These are my first steps with the maple software and there is the following problem to answer.

a) I have to define a sequence L who is dividing a interval between [0,2*pi] in 20 sub intervals.

    The output of the different values should be in decimal numbers.

I can get the tangent line by using "Tangent"  Then what about the normal plane


Tangent(t->{t, t^2, t^3}, t = 2)


I need to filter a 2D Matrix based on the values in one of its columns.

Let's have a 2D Matrix like this one:

[1, 2]
[-2, 3]
[3, 18]

Now let's suppose we want to remove all rows with a negative number in the first column (second row in our example).

One possible solution would be to iterate over the whole Matrix in a for-loop removing rows one-by-one, but I was hoping for something more elegant (and hopefully faster).

Dear Sir/Madam:

I have the following simultaneous equations to get the 4 unknow variables
by maple engine. However, the maple did not give me anything. Actually,
the exact solutions exist in the educational text. Now, I am trying to get them
on maple. Why it does not work at all?
Please let me know how to do.

Thanks in advance.

eq1:=A2*t2*exp(zt*t2*om)*sin(t2*wd)+A3*t3*sin(t3*wd)*exp(zt*t3*om) = 0:

Latex to maple

I have the latex code

\lim_{(x,y)\rightarrow (0,0)}\frac{e^x+e^y}{\cos x-\sin y}

Can this latex language allow the entry of Ctrl+V

how can I solve this equation

how can I solve this equation

This is the first time I used the Maple software so I haven't known clearly about it. could you give me a document about " How to use Maple ".

Thank you.

i came into some questions when i wanted to solve a pde systerm as follows:

> pde := diff(u(x, y), y, y, y, y) = 0;
> sys := [pde, u(x, 0) = 0, u(x, a) = F0, (D[`$`(2, 2)](u))(x, 0) = 0, (D[2, 2](u))(x, a)-beta*(D[2](u))(x, a) = 0];
> pds := pdsolve(sys);
Error, (in pdsolve/sys/info) found functions with same name but depending on different arguments in the given DE system: u(x, a), u(x, y). It is required an indication of the dependent variables



I am trying to solve the following equation:




A, B, C and D are all sum of sins and cosines.


Should I use COMBINE first and then solve, I am not getting what I want. hope there is a way to evaluate this function.


Looking forward to your kind replies

Thanks in advance





Is there anyway to disable the superscript so it works exactly like in Classic Maple, so the whole equation stays inline? Having it go to where it should be makes marginally easier for me to read it, but having to press the right arrow to leave the superscript is extremely annoying and time consuming.

Edit: example: I want it to stay as 10^5 instead of 105, at least while I'm writing.
