i have 3 equations which contains both numeric and symbols, how can i seprrate these to ?
for example :

> restart:
> eq1:=a[1]^3+a[2]+a[3]^2+50;

> eq2:=a[1]^2+5*a[2]+a[3]+44;

> eq3:=a[1]+a[2]+a[3]^2+74;

i want maple to seprate these three equations in two vectors,first vector including symbols and second one includes numerics , like this :
V1:=<<a[1]^3+a[2]+a[3]^2>,<a[1]^2+5*a[2]+a[3]>,<a[1]+a[2]+a[3]^2>>;

V2:=<<50>,<44>,<74>>;

eq:=<<eq1>,<eq2>,<eq3>>;

so that 

is(V1+V2=eq);

gives me the answer true.
tnx for help.

2. Give the Maple command(s) to compute \frac{\partial^8 f}{\partial^5 x \partial^3 y} for f(x, y) = e^{2x+ cos(y)}.

How do I define a function from a graph in a plot? 

Or how do I find the intersection between two lines? I have to find the intersection of 2 lines in a graph, while one of these lines consists of 2 different equations dependent from the same variable. 

 

Thanks in advance. 

Hi! I am a newbie in Maple. For several days trying to read help but no luck. Search here for "solve tensor equation" does not help either.

There are tensor package and physics package but in both helps i have not found how to solve simple tensor equation AijmnBmnkl=Cijkl. Let's say A and C i create as analytical arrays and then create tensors on the base of them (not Arrays - for some reason the tensor cannot be created on the base of Arrow...

Why can't Maple solve this integral equation using intsolve? May be my error entering it?

sys:= diff(y(t),t)=2-t^2/2 - 1/4 * int(y(t1),t1=0..t);
intsolve(sys,y(t));

Error, (in unknown) invalid input: diff received 0, which is not valid for its 2nd argument

I solve it by hand, and wanted to verify the solution. I get y(t)=C* sin(t/2) -4*t and C can be found to be 12
thanks,

Let z be a complex number and p your conjugate. how to solve the equation

(2z-3)(-3p+4)-(2p-3)(-3z+4)=0   with maple?

I'm given this equation: f := proc (x) options operator, arrow; x^5-51*x^4+939*x^3-7685*x^2+28800*x-40500 end proc and I have to find the decimall value of f(ln(3*Pi)+8*e^4+sqrt(8+sin(4))). How do you program this in Maple?

How can I Solve this using maple?

Differential equation:
y(n+2) + 7/10 y(n+1) + 1/10 y(n) = x(n)

x(n) = 1
y(0) = 0
y (1) = 1

Use Z-transformer to define y(n).

Solve y(0), y(1), y(2), y(3) y(4) and y(5) 

Any one?

hi

I have a program with system of equations in wich my equations are in 8 matrices (4x4) with 64unknown parameters

i have run it but after 10 minitutes maple gives this massage:

"length of output exceeds limit of 1000000"

is there any way to solve this problem?

Hello

I am trying to solve an equation for optimization purpose, However I always recieve the message below:

Warning, solutions may have been lost

The Maple code is as follow:

PTE2.mw

 

I would be thankful if anyone can help me to solve this problem.

 

Cheers

I want to find all values of m such that the equation (x-m)*(x-2*m-1)*(x+3*m-2)*(x+m+3)=0 has two positive solutions and two negative solutions. How to solve this problem with Maple?

Hi every body

I want to solve a differential equation y'(t) = sqrt((f-1)/(t^f-t)) and get an answer in terms of ordinary function.is it possible. thanks 

hello,

I need to find a sollution for equation in maple 14

a*s = b mod c, where a, b, c are know integers, for example

Dear members,

I am trying to solve a maximalization problem, but in stead of solving my problem Maple only displays the equation that I am trying to solve.

Example:

>  Sigma_max:= maximize(-N/(b*h)+(-EI*(diff(u(x),x,x)))*0.5*h/I, x=0..l = sigma_t;

sigma_max:=maximize(-0.400000cos(0.25pi)N+564e*N*x .....etc...., x = 0..250)=1.43 106

It's interesting that every continuous piecewise linear function can be specified by one explicit equation with absolute values​​. The procedure JoggedLine carries out such conversion.

Formal arguments of the procedure: 

A - a list of the coordinates of the vertices of the polyline or the continuous piecewise linear expression defined on the entire real axis.

B (optional) - a point on the left "tail"...
