Do you have any suggestions algebraically to solve the constants when the problem is a polynomial? Anything above a second power f(x) becomes such a complete mess.

Why yp = At+B necessarily

Thanks :) !

what is there is no y term on the left hand side so you cannot solve for B?

hello sir.. why is it just At+B? why not just A or At^2+Bt+C?
thank you in advance

could you look at this problem?
Show that function y= e^2x (2cos(3x)-sin(3x)) satisfies the equation y''-4y'+y=0

so does the Yp need to be linearly dependent with the Yc?

can we apply this method for 1st order differential eqns

Could you explain the inverse operator method in case R(X) !=zero ?
