Cracking The Ap Calculus ab Exam 2018

The  height  of  each    rectangle   is  found   by  taking  the     difference  between     the     endpoints   and

dividing    by  n.  Here,   the width   of  each    rectangle   is      =   .

We  find    the bases   of  the rectangles  by  evaluating  y   =   2x  −   x^2     at  the appropriate endpoints.

= ; = ;

    =    ;  and     =   .

Therefore,  the area    is      =   .

We   will    find    the     exact   area    by  evaluating  the     integral    dx.     According   to  the
