You are going to do 6 rectangles between x = 0 and x = 3

for LRAM, you use the height at the left.

(I am not going to calculate them for you)

so use

f(0)=

f(.5)=

f(1)=

f(1.5)=

f(2)=

f(2.5)=

for the heights

The base of each rectangle will be 3/6 = .5

add those all up and multiply by .5

Now to do it for RRAM

use:

f(.5)=

f(1)=

......

f(3) =

then add those 6 up and multiply by .5

o do it for the middle points use

f(1/4)=

f(3/4) =

f(1 1/4) =

.......

f(2 3/4 )=

and again multiply by .5, the base of each rectangle
