ay' + by = 0, integrating factor correct answers µ = exp(∫(b(t)/a(t))dt) ay' + by = h, variation of parameters correct answers Guess y_p=g(x)f(x), where f(x) is the homoegenous solution, and plug into l(y)=ay' + by = h. Result: g' = h(x)/[a(x)f(x)]. We have to INTEGRATE g' and MULTIPLY it by f. ay' + by = h, general solution correct answers homogeneous solution + particular solution Analytic definition correct answers If f is a smooth function, then f is analytic at x₀∈‖R...
