## how do i display divergence of vector in...

Maple

Hello,

I'm writing an equation that has a term including divergence .. i'd like to print that as the sum of the derivatives

for example instead of nabla(u) display it as ux+uy+uz

## How to solve 2 equations and use output...

Maple

I've 2 equatoions that i wish to solve to get 2 values, which should be used as an input for the next step and so on,

I've managed to produce the equations, but i can't force the code to use the output of the first loop T1[1] and T2[1] into the 2nd loop and so on

It produces only equations, I'd appreciate it if anyone could tell me how to do that into an array or something similar

## how to set variables as constants when d...

Maple

Hello,

I need a little help...

what I want to do, if i have 3 equations  with multiple variables and i want to get derivative of some of these variables wrt other variables while setting others as constants

here in the example

1st i thought the last equation should have partial m / partial f ... how can i get that

2nd if ,another problem, i wanted to set z as a constant so it won't consider getting its derivative, how do i get that

## how do I introduce vector and differenti...

Maple

Hello

I was trying to introduce vector r_vec that has 3 components in x,y,z

I've attached my file, I've 2 questions here

first, why isn't the vector shown in as r_vec = () ei + () ej + () ek instead appears as a column vector

second, why doesn't it accept differentating

thank you
