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.
4. a. Can you simplify the sum of the two leading terms to remove the angle parts: 22 cos? (0) arz + sin() arz =? Hint: it's really easy-what is the simplest trig identity you know? (5 pts) b. Now let's deal with these two "middle" terms. We can show that if you add them together then: How? Let's start by acting Y(r).() on the first term above: - (inco)cosapopt(cos(m)opsin cm) - k - (sin(e) cos() 0400:46 = - (sinca..cos(m)cm)...
