Hi,

I know all the necessary computational steps to create a Linear Regression line, but I am having trouble making it into a succient procedure. I have to make a 3 procedures for three methods, minimizing Vertical distance, Horizontal, and lastly, Diagonal. 

I uploaded an example of my work to compute a linear regression line, minizming vertical distance. I have all the necessary steps for horizontal and diaganol as well. 

I have to write a procedure that finds four positve numbers with a two decimail digits such that their sum and product is equal to 7.11. i.e a+b+c+d=a*c*b*d=7.11

I know i have to use loops but I have no idea how to start

please help , my deadline is near

On my keyboard, Cntrl = action for evaluating an expression inline does not work. The reason is that = is the upper level action (with the shift key) on a key with 0 at the lower level. Doing Cntrl Shift = does not work either. How do I get this done on my keyboard?

Hi,

is the series expansion for the following expression bugged in maple or am I missing some crucial thing of series?

series((1/epsilon-log(4)),epsilon=0);

results in epsilon^-1 -2 -2*ln(2)

for xmaple 16.01. The console version does not add the wrong term "-2".

Apparently it works here: 

Hi, i have the following question: i've been asked to investigate the following family of functions:

f(x,y)=(be^a(x)^2)+y^2

the question is: How does the shape of each curve depend of a and b.

Thank you

Hello every one,

I want to plot two parameters against each other from a system of ode.

The system is

restart:

with(plots):with(LinearAlgebra):

Eq1:=diff(f(eta),eta$3)+f(eta)*diff(f(eta),eta$2)-diff(f(eta),eta$1)^2-M^2*diff(f(eta),eta$1)+M^2*b+b^2=0;

Eq2:=diff(g(eta),eta$3)+f(eta)*diff(g(eta),eta$2)+(Lambda-2*diff(f(eta),eta$1)-M^2)*diff(g(eta),eta$1)+diff(f(eta),eta$2)*g(eta)=0;

N:=10: M:=0.1:

How do i show that i am a student before my liscence expires.

Hello,

I'm trying to solve the effects (deflictions, tensions, etc) of a load on a timoshenko beam. It uses two partial diffential equations, wherein q is the load:

> PDE1 := kappa*G*A*(diff(y(x, t), x, x)-(diff(theta(x, t), x)))-rho*A*(diff(y(x, t), t, t))-q;

> PDE2 := E*J*(diff(theta(x, t), x, x))+kappa*G*A*(diff(y(x, t), x)-theta(x, t))-rho*J*(diff(theta(y, x), t, t));

The boundary conditions are that in the corners the moments (derative of theta...

Hi, I'm working on fitting model. For some reason is taking way too long to evaluate it actually hasn't finished it at all. Im running on i7. Thanks for any help. this is my code:

Can somebody, please, try this command in Maple 16 (or at best Maple 16.02)?

Student[Calculus1][FunctionChart](x*exp(1/x));

In Maple 15 I get the graph in about 1s, however in Maple 16.02 it loads about 20s and it is even not as perfect as is in Maple 15. Furthermore, when I try to evaluate

st:=time():
Student[Calculus1][FunctionChart](x*exp(1/x));
time();

it says that it lasted only 1-2s. There is some problem...

I would like to create a single animated plot with two components.

The first component being an animation of the graph of r = 2*sin(theta) as theta varies from 0 to 2*Pi in the r-theta plane.

The second component is another animation, simultaneously showing how the graph of r=2*sin(theta) is generated in the polar coordinate system.

I am able to produce each component separately rather easily using the plots:-animate( ) command. What I am looking for is somehow being able to use ...

Hi im using maple 16 and defined a vector field that is lengthy below,

(and yes i defined with(VectorCalculus), and SetCoordinates(cartesian(x,y,z)) (x,y,z is subscripted)

And i am using a type of line integral for the work of a particle's path through a force field which i defined here as Z.

From the page:

http://www.maplesoft.com/products/system_requirements.aspx

it would seem like ubuntu 12.04 is not officially supported for Maple 16. Could someone from Maplesoft comment if there are plans to add support with perhaps a patch? or will we have to wait until Maple 17?

I need to update for certain sofware, but would want to make sure I can run maple in an uncompromised way.

thanks
