Could someone please help me with this question? Find the general solution of the differential equation: f''(x) = sin(2x-4) Do i simply integrate both sides twice? What method of integration do i use?

What method of integration do i use? Hi remember. Welcome to MHF. y'' = d/dx (y') = sin(2x-4) Integrate w.r.t to x: Don't forget your constant of integration. Write y' as dy/dx & integrate w.r.t x.
Thanks! Also, say for example the DE was changed to this: I take it I just integrate the sin and cos parts of the equation seperately because they are added and not a product of each other?
