I have four equations:

eqs:={8x-5z=0, -5y-2x=0, 2z-8y=0} and 13x-4y+9z=1

I've been trying for the past hour to solve both equations for x, y, and z and have not been successful.

What commands do I use to solve this problem?

I want to find all integral solution of the equation x =

Pi/9+2*k*Pi/3, where k is integral numbeer and 1 <= x <=2^Pi.

This is my code.

restart; solve([Pi/9+2*k*Pi/3 >=1,Pi/9+2*k*Pi/3 <=2^Pi],k);> evalf(%); > f:=k->Pi/9+2*k*Pi/3; > seq(f(k),k = 1..4);

Please help me another way. Thank you.

Please write for me a code this problem.

Write the equation of the plane passing through the two points A(1,-2,4), B(3,5,-1) and make a least angle with the plane x + y + z + 1 = 0.

Thank you very much.

Let A(2;-2;3), B(4;-5;6) and (M(1;2;3) be three points. Write the equation of the plane (P) passing through two points A and B

Write the equation of a pane (P) which passes through the point E(2,1,0) and F(1,2,1) such that distance from the point A(1,-2,-1) to the plane (P) twice distance from the point B(2,4,3) to the plane (P).

My main idea is based on, if the line (d) passes through...

I am learning about programming; I have this equation:

2*K2*alpha*t=ln[(A0+E(beta-1/2)/(A0-E(beta+1/2)

The values of t, E are a list of values.

and K2 alpha and beta are unknown but i dont know how to do for graph the part of ln vs time and fit it to a line.

Hello,

I'm trying to solve the following system in Maple but it doesn't show me any solution:

where x(0)=0 and y2(0)=0 , k>0,...

I have a system of three non-linear coupled ODEs. I am trying to obtain the zeroth order, first order and second order equations and their boundary conditions using the perturbation technique. I then need to solve them. I wrote the following MAPLE lines for the purpose.

restart; N := 2

Eq[1] := diff(f(eta), `$`(eta, 3))+(m+4)*f(eta)*(diff(f(eta), `$`(eta, 2)))-(2*(m+1))*(diff(f(eta), eta))^2-(2*(m+1))*h(eta)-(.5*(m-2))*eta*(diff(h(eta), eta))

Eq[2] := g(eta)-(diff(h(eta), eta))

Hi,I need help of your expertize in solving the following queries:I would start with a sample equation:Eq1 = u_{xxxx} + u_{xxyy} - v_{xxxy} - v_{xyyy} where u_{xxxy} represents 4th order pde of u i.e. d^4/(dx^3 dy).I get a equation similar to Eq1 (but quite complicated) on solving the equilibrium equations. I would like to collect the similar derivativesfor variable u and v together likeEq2 = d^2/d x^2 ( u_{xx} + u_{yy} ) - d^2/dx dy ( v_{xx} + v_{yy} )

Hi!

I have seven curves (expressions) R:=f(x) for different value A.1. How to Plot all curves on one 3D spece plot?2. Hot to get (fit) surface equation R:=f(x,A) from all 2D curve?

Hey there, this is my first post here, so hello to everyone.

I have (so far) one question. I have a circle equation like

x^{2}+y^{2}-6y+6=0

I know, that on a paper, I can convert it to the "normal" circle equation, from which I can read the middle point and radius of the circle. And now my question is, how to convert in in maple? I am using the 11th version.

I have tried solving this equation and (x-a)

When I use the solve command in Maple15 nothing happens. I just want to solve for V and Cf.

Does maple not like implicit equations? The file is attached

It is the mathematica code for bifurcation diagram of the model that i am working with now. is there anybody who can translate it into maple code? or does anyone can help me with making a bifurcation diagram for such a ODE system in maple??

Thanks in advance

Let's say if given a expression y(x)=1/x+sinx, how to find the equation which y(x) satisfies by using Maple?

How can i trunc (find closest integer) each element in a matrix ?

This is my matrix equation:

for n to 20 do 'CD'^n, 'F' = evalf(C[1].D[1]^n.F[1]) end do

And i want to show "trunced" results
