with(VectorCalculus):

SetCoordinate(cartesian[x, y, z]);

F := VectorField(<x^2,y^2,z^2>);

Divergence(F);

Error, (in VectorCalculus:-VectorField) no coordinate names were given

Error, (in Vector) dimension parameter is required for this form of initializer

Hi, was wondering if any of you could help me, when I try and find the real part of a function to plot, I get a float(undefined) error, however by just using evalf if gives gives me the real and comlex parts.

The function i want to find realy parts for is f(x).

Thanks,

Matt

Hey,

I know this might seem a bit trivial but I'm trying to get Maple to use iteration to get the shortest path between two points given initial conditions that aren't a straight line. (I'm learning how to do it in the simplest form before moving on to a 3D problem.)

So I have a initial set of points that are to be moved during the process and split them into their x and y components so there's a set of x[j]'s and y[j]s.Then I defined a couple of procedures to use in the iteration.

I have the following equation, I want to solve it for b keeping a and c fixed.

5*b^5+(60-5a)*b^4+(125+50c-80a)*b^3+(594c-445a-775)*b^2+(2324c-1005a-3270)*b+3000c-750a-3000=0.

How to solve it in maple?

Hello! I have the task to calculate the two angles of an 3d linkage. now in step 11 i have these two equations:

I have to solve these for phi, that is the angle I'm looking for. But the solution for phi should be indepented of psi. alpha and beta are variables. Everything else are known constant values.
What I tried: I solved Gl7 for psi (step 12...

Can someone please solve only #19 and #25 using Nwton's method in Maple. I really appreciate it.

The questions are attached. Thank you

An intersection in my neighbourhood, currently controlled by a 2-way stop, is under consideration to become a 4-way stop.  This means the traffic that currently has the right-of-way will be required to come to a complete stop, wheras previously they could have coasted down the hill, and accelerated up the other side.   Politics aside, I was curious to explore the following question:

You have been asked to design a one-liter can shaped like a right circular cylinder. What dimensions will use the least material?

-I really need help on how to correctly plug this into my computer. Thank you in advance.

Is it possible to use something like

Given an n*n matrix M an its rth row and cth column element m[r,c].Suppose m[r,c] = c*m[r-1,c]+a*m[r-1,c-1] and m[0,0]=1, m[0,k]=m[l,0]=0 for k>0,l>0.The letter "a" denotes a constant number and n can be any non negtive integer.
