Please use ONLY the variation of parameters method if possible. Thank you! 1. Solve the following differential equations using the method of variation of pa- rameters (for first order equations), or any other acceptable method: cos x + (sin x) y = 1 Ans: y = sin c +C cosx. (b) (x+1) 7 + (x + 2) y = 2xe-* Ans: (x+1)e’y = 22 + C. 2 + (3x + 1) y = e-32 Ans: y = e-3x + Cx-1e-3r.
