Problems listed from 7.5 remain onthis week’s syllabus.For 7.7, see example below; decimal approximationswill not be on exam, answers as explicit sums will be.7.8 - 5,8,9 and 8.2 - 5, 8, 10, 11 as covered in class todaProblem 7.4.20:EvaluateZx2(x-3)(x+ 2)2dx.Solution:The method of partial fractions says there areA, B, Csox2(x-3)(x+ 2)2=Ax-3+Bx+ 2+C(x+ 2)2.As in previous cases, we first clear denominators,multiplying both sides by(x-3)(x+ 2)2,sox2=A(x+ 2)2+B(x-3)(x+ 2) +C(x-3).
