1. The problem statement, all variables and given/known data Find the general solution to the differential equation: y' - y = sinx + cos(2x) 2. Relevant equations 3. The attempt at a solution r - 1 = 0 r = 1 y1 = c1e^x i don't really understand how to pick the yp... do you just guess? i tried both Asinx + Bcos(2x) and Acosx -2Bsin(2x), and neither really worked out... but i may be doing it all wrong. my teacher went over it quickly, and our book doesn't cover it. 1. The problem statement, all variables and given/known data show by means of the wronskian, that the second order differential equation y" + a1(x)y' + a0(x)y = 0 cannot have three linearly independent solutions y1, y2, y3. 3. The attempt at a solution i have no attempt on this problem, because i have no idea what to do. i know how to do the wronskian (just the determinant), but that proves absolutely nothing. thank you for any help!
