The  area    enclosed    by  the     hypocycloid     (shown  above)  with    parametric

equations   x   =   cos^3 t and y   =   sin^3 t  as  shown   in  the     above   diagram     is

Suppose the following   is  a   table   of  coordinates for y   =   f   (x),    given   that    f   is

continuous  on  [1, 5]: 

If  a   trapezoid   sum in  used,   with    n   =   4,  then    the area    under   the curve,  from

x   =   1   to  x   =   5,  is  equal,  to  two decimal places, to  6.88
