Suppose we want to find the area between

() 2fx x=− and () 0.5 1gx x=−from x = -2 to

the first positive intersection of the two graphs.

From the shaded screenshot shown above

right it can be seen that to find the area we

need to split it into two sections, with the

boundaries being -2 and the two

intersections.

The shortcut here is to use

Intersection

to find the first intersection, storing the results

into memory variable A.

We then do the same thing for the

second intersection, storing the

result into B.

We can now calculate the area in the HOME view, using

−

for the first

and

f− for the second. Use to duplicate the first integral and edit it

to adjust the functions and limits.

Finally,

the two solutions and add them

to give the final answer.
