# First order nonlinear DE

mike79
dear friends,
i need to solve analitically(also by means of approximate methods) the following nonlinear differential equation:
(A+BTs^(3))*dTs/dt+C*Ts^(4)=D

where Ts is a function of t. A, B, C and D are costants. the initial condition is Ts(0)=Ti.
I would be so grateful if anyone can help me.

Regards
Michele
