Hi everybody:

tnx...

Hi everybody:

I have one equation:

EQ := V^3-R*T*V^2/P-(B^2+P*B*R*T*sqrt(T)/(P-A))*V-A*B/(P*sqrt(T)) = 0;
how can I obtain these derivatives:

How can I plot Y in terms of X (Y is the vertical axis and X is the horizontal axis) in below equation with Maple?

X^3-24.478115*X^2/Y-(0.2038793409e-2+19.08455282*Y/(Y-97.539))*X-.2550630228/Y = 0

X:=0..50

Y:=0..1

Hi

I will write a code that to take one matrix (for example A) and produce B matrix, how write this code in Maple? the A matrix is optional.

A:=Matrix([[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]]);

B := Matrix([[10, 11, 12], [7, 8, 9], [4, 5, 6], [1, 2, 3]]);

Tnx...
