Question

fx px 3. Solve the following initial value problem (13.2.20): Differential Equation: = (sin t) î - (cost)ġ + (4 sint cost)k Initial Conditions: (0) = î - R op (0) = î

Answer 1

integrate, do = (sine) T - (cost) ] + G sint cost it - Sasa = Seint i - rost It 2 siner f] at d = { cost in sint i + 2 froszt) &] + (cii + 25 +G;t) as ds = [frost+c) i tf sint tro) it froszt tes ] at to, dsto) = {trosco) +c) it tsinot cz)j + tros 26) +3) El Ta = (-1461) T+to+(2) J + (Ecoso) try t compare the terme Itta) | [oz cz] l as fltry) da = {{cost tzi + (- sinto)] + troszt to) il integrate on both sides

integrate on both sides S di d = 5 [12-cost)i + (sint)] + (1-1082) It utro 50 = [(l2t - sini De di) it 6-6-cost)+d)] + [t-singhe dhe 800) = [ (209)-sinca) tdi) 74 (cos6) +)] + (0-sing (9)+d3) 1] (1 k) = [ (0-0+ d.)i + ((+ d)] + 10-ofds) f] compare the terms 814) =(24-sint +) + (cost-1)] + 6 - swt )R] < please rate the answer -
