Given the second order non linear BVP

(ƒ')^n = 1 + γ θ …..……………………… 1

θ" + (λ +n+1/ 2n +1) ƒ θ' - n (2 λ +1/2n+ 1) * ƒ' θ = 0 ………… 2

Prime in the above eqn’s describe partial differentiation with respect to η

Boundary conditions are
ƒ (0) = 0, θ'(0) = -1
ƒ' (∞) = 0, θ(∞) = 0

can any let me know how the above PDE equations are converted to ODE's

In order to have a PDE, your equation must contain
derivatives with respect to at least two independent
variables.
You say η is one of them. What is the second one,
and where does differentiation with respect to it occur ?
