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)

Hello.

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 variablesby 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 themon maple. Why it does not work at all?Please let me know how to do.

Thanks in advance.

restart;eq1:=A2*t2*exp(zt*t2*om)*sin(t2*wd)+A3*t3*sin(t3*wd)*exp(zt*t3*om) = 0:eq2:=A2*t2*exp(zt*t2*om...

Latex to mapleI 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

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

Hi,

I am trying to solve the following equation:

S:=(A+jB)*conjugate(C+jD)

where

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 10^{5}, at least while I'm writing.

Hello,

I'm new to Maple and am using it to solve linear and non-linear differential equations.

I can solve and plot linear DEs using a couple of methods. Im trying to solve a non-linear DE and i could find the series solution using dsolve. But given certain initial conditions, is there any way to plot or see the nature of the behaviour of the DE? I just want to see how the DE will look like maybe for certain points up to a certain level of accuracy. Is there any way to do that?

Hi all,

I have an array [1..2503] y-axis for different values, x-axis [0..180],

when I plot these two arrays its not possible. but if I change x-axis [1..2503] then plot is ok... I want to plot x-axis [0..180] and y-axis [1..2503]

I want to find the diffrential equation of

Hi everyone,

Here is the code:

Ralpha:=sqrt(d)*IdentityMatrix(2):

alpha:=Array([WienerProcess(Ralpha),WienerProcess(Ralpha),WienerProcess(Ralpha),WienerProcess(Ralpha)]):

alpha1:=k->Vector[column]([[alpha[1](k)[1]],[alpha[1](k)[2]],[alpha[2](k)[1]],[alpha[2](k)[2]],[alpha[3](k)[1]],[alpha[3](k)[2]],[alpha[4](k)[1]],[alpha[4](k)[2]]]):

Finance[ExpectedValue](alpha1(0)[1]*alpha1(0)[1],timesteps=100,replications=10^4);
