I need answer for Ques no.1 from the attached document. Thanks in advance.

MATH 127 1 HOME WORK 2 Due : Wed Oct 3 @ 0830 1 ) An alternate method to compute a definite integral is to use :" \\ } ( x )ax = lim\\ f ( *` ) Axis 1 = 1 Here the subintervals do not always have equal width . In other words , the width of each* subinterval Ax ; may depend upon i . Note that this also changes our usual formula for *. . We* Will see how we can compute S Vidx using this formula . a ) If Ax ; = 21 - 1 72 , show that LAX ; = ] b ) Use xi = _ and the Ax ; given in part a ) to compute S Vardx using the formula :" [` ( x )ax = lim { Him > F ( X )AX , 2 ) Express the limit as a definite integral .
