Answer 6

so, what this gives you is:
\[
A\approx h[f(x_0)+f(x_1)+f(x_2)+f(x_3)]
\]

Answer 7

h = (1-0)/4=0.25
x0 = 0; x1=0.25; x2=0.5; x3=0.75
plug and add em up

Answer 8

this is for lower

for upper:
x0=0.25, x1 = 0.5; x2=0.75; x3=1.0

Answer 9

@hayatabz1 is that what you did?

Answer 10

@electrokid i dont understand how to solve this problem I am confused. I did do that but got the same thing for upper and lower...

Answer 11

as long as you did that and did the computations correctly, you should be good.
