How Can I Solve This Differential Equation?

Click For Summary
SUMMARY

The discussion focuses on solving the differential equation \(x \frac{dy}{dx} - 2y = x^2 \cos(x)\) with the initial condition \(y(\frac{\pi}{2}) = 0\). A suggested approach involves dividing the equation by \(x\) to facilitate the use of an integrating factor. This method allows for the transformation of the equation into a more manageable form, ultimately leading to a solution.

I'm having problems solving this differential equation:

x*dy/dx-2*y=(x^2)*cos(x)

y(pi/2)=0

Thanks

Can one think of a way that xy'-2y looks like the derivative of a quotient?

you can always divide by x and then you know...integrating factor it
