Finding the Area between Curves
Problem
Find the area of the region bounded by
f(x) = 300x/ (x2 + 625)
g(x)= 3cos(.1x)
x=75
Procedure
1. Press z. Select the default mode settings.
2. Press p. Set the viewing window.
Xmin=0 Ymin=L5
Xmax=100 Ymax=10
Xscl=10 Yscl=1
Xres=1
3. Press o. Turn off all functions and stat plots. Enter the upper and
lower functions.
Y1=300Xà(X2+625)
Y2=3cos(.1X)
