How do you estimate the area under the graph of f(x) = sqrt xf(x)=√x from x=0x=0 to x=4x=4 using four approximating rectangles and right endpoints?
1 Answer
For this problem:
the number of rectangles
To find all of the endpoints of subintervals, start at
All endpoints:
The right endpoints are:
The heights at the right endpoints are:
Call the areas of the rectangles
Then the approximation we want is:
