Question

Estimate the area under the graph of f(x)=e^−5x^2 from x=0 to x=2 using the midpoint rule with n=4

Answer 1

ohh this is riemann sun

Answer 2

you need to the the change of x (triangle sign x)
the change of x: (b-a)/n so, (2-0)/4

so change of x is 1/2.

Answer 3

just know the left hand, right hand, and midpoint formula and things will be easier.

if you can use the calculator just put everything like this:

Answer 4

n
rieman sum sign [(fx) x (change of x)
i=1

Answer 5
