SUMMARY

The discussion focuses on solving the nonlinear differential equation 2y' - (x/y) + x^3 cos(y) = 0. Participants highlight that standard linear ordinary differential equation (ODE) techniques, including Bernoulli, Cauchy, and Legendre methods, are ineffective due to the presence of the cosine function in the equation. The consensus is that specialized methods for nonlinear ODEs are necessary to approach this problem effectively.

PREREQUISITES
  • Understanding of nonlinear ordinary differential equations (ODEs)
  • Familiarity with Bernoulli differential equations
  • Knowledge of Cauchy and Legendre methods for solving ODEs
  • Basic principles of exact differential equations

Homework Statement



Solve the follwing differential equation
2y'-(x/y)+x^3 cosy = 0 solve?

Homework Equations



Linear Differential equation: y'+py=q
exact differential equation: Mdx+Ndy=0

The Attempt at a Solution



both of the methods i have applied ... but didnt work
later i tried it as Bernoulli Differential equation in x... but variables are not coming in

x' + px = q form...


kindly help me or give me hint to solve the above differential equation.

This is a non-linear ODE because of cos y. Standard linear ODE solution techniques won't work.
 
Give me some hint ... I have also tried Cauchy and legendre methods as well ... But no one works here
