Find the general solution of the following 2nd order differential equation by undetermined coefficients method:
a) 1/4 y” + y’ +y = x2 – 2x
b) y” + 4y = (x2 – 3)sin2x

thanks all
:)
 


Whoops! It looks like you might have missed the post titled, "Read Before Posting".

Are you able to explain where you're stuck, in these exercises? What have you done so far? Have you seen the "undetermined coefficients method"?

Please be specific, so that we can determine how to begin helping you. 8-)
