MATH 132 FINAL EXAM F12M132.4.1 This exam should have 20 multiple choice questions, 5 points each. If you don'thave a PENCIL to mark your card, please ask to borrow one from your proctor.Write your ID NUMBER (not your SS number) in the six boxes on the side of youranswer card, and then shade in the corresponding numbers. The needed data fortrigonometric functions and power series is contained on the last page.1) Use substitution to evaluate tan'0/41$ #ÐBÑ † =/- ÐBÑ .BEÑ !FÑ !Þ"&GÑ !Þ#&HÑ !Þ$&IÑ !Þ%&J Ñ !Þ&&KÑ !Þ'&LÑ !Þ(&IÑ !Þ)&N Ñ "2) Use integration by parts to evaluate '1eB 68ÐBÑ .BÞ#EÑ %Þ!)FÑ %Þ"'GÑ %Þ#)HÑ %Þ$%IÑ %Þ%#J Ñ %Þ&(KÑ %Þ'*LÑ %Þ(%MÑ %Þ)#N Ñ %Þ*$132F12.4.23) Using partial fractions, find a solution to ' "B B2.BÞ ÐB !
