## How to use dsolve with boundary conditio...

Maple 2018

Hi,

I'm currently solving an equations where the boundary conditions is at infinity. I'm trying to solve it by using dsolve but i can't seem to find a solutions. Here is my equations:

ode1 := diff(f(eta), eta\$3)+(diff(f(eta), eta\$2))*f(eta)-(diff(f(eta), eta))^2-M . (diff(f(eta), eta))-A . (diff(f(eta), eta)+(1/2)*(eta . (diff(f(eta), eta\$2)))) = 0;

ode2 := diff(theta(eta), eta\$2)+Pr*(f(eta) . (diff(theta(eta), eta))-(diff(f(eta), eta)) . theta(eta)-A . (theta(eta)+1/2 . eta . (diff(theta(eta), eta)))) = 0;

and my boundary conditions are:

bcs := f(0) = 0, (D(f))(0) = 1, ((D@@2)(f))(inf) = 0, theta(0) = 1, theta(inf) = 0;

The value of Pr=7, M=1 and A=[0,1,2,4]

Thank you :)

Can you help me please. i have a problem with the coding where i obtain the graph different with the journal that i have been referred to, Here is the codes, the graph that i obtained and the grpah from the journal. Thank for your help.
