To find the area betwen y = x and
x^2.
The intersection points of y = x and y = x^2 is given
by:
x= x^2.
Or x-x^2 =
0.
Or x(1-x) = 0.
So x= 0 , Or 1-x = 0
, Or x = 1.
So the area between curves is to be found from x= 0 to
x = 1.
If we draw the graph , y = x is above x = x^2 from x= 0 to x
= 1 .
Therefore area between y = x and y =x^2 is given
by:
Area = Integral (x-x^2)dx from x= 0 to x =
1.
Area = {(x^2/2 -x^3/3 at x= 1} - {(x^2/2 -x^3/3 at x=
0}
Area = { 1/2-1/3}- 0
Area = (3-2)/6
= 1/6.
Therefore the area between the curves = 1/6 sq
units.
