## Polarplot3d of ODE system solution...

Maple 12

I am trying to have the output of DETOOLS as 3dpolarplot. As in the following example:

EF := {2*(diff(w[2](t), t)) = 10, diff(w[1](t), t) = sqrt(2/w[1](t)), diff(w[3](t), t) = 0}; with(DEtools); DEplot3d(EF, {w[1](t), w[2](t), w[3](t)}, t = 0 .. 100, [[w[1](0) = 1, w[2](0) = 0, w[3](0) = 0]], scene = [w[1](t), w[2](t), w[3](t)], stepsize = .1, orientation = [139, -106])

how can I get the output as a polarplot in 3d where, w[2] and w[3] have range 0..2*pi.

## Using numerical solution of ODE...

Maple 12

Hi,

I have a first order differential eq. for some variable say \$r(x)\$, where \$x\$ is the independent variable.

After solving this differential equation numerically, I want to use its solution in other expression for \$r(x)\$ and plot the expession with \$x\$.

Please let me know how to do it.

Dear all,

I want to know how can I solve a fourth or higher order equation to find out its roots, actually coefficients of each power terms itself are functins of other parameters not constant.

Regards.

## operators in GRTENSORII...

Maple 12

how gr operators work?

I tried to run example given there but it is not working,

where can I get more examples to understand working of Gr operators work?

specially for raychaudhuri equations.
