Find the area in the second quadrant bounded by the curve 

y = x3+4x2-x-4 and the x-axis.

 

A. Using the Horizontal Strip
2. Find the area in the second quadrant bounded by the curve y=x' +4x² – x - 4
and the x- axis.
From the figure on the left, the area of the strip
is xdy. The total area can be found by running this
strip starting from y, going to y, given by the
dy
formula:
A =
xdy
y1
B. Using the Vertical Strip
From the figure on the left, the area of the strip
is ydx. The total area can be found by running
this strip starting from x, going to x2 given by the
formula:
X2
A =
ydx
ED
