There are many good Riemann Sum calculators online.
google will lead you to them.
Then just plug in your numbers.
where do you get stuck?
The department of water resources is measuring the width of a flood plain, as shown by f(x). The water measurements (x) are taken in 15 foot increments as shown in the table below:
x: 0 | 15 | 30 | 45 | 60 | 75 | 90 | 105 | 120 |
f(x): 0 | 18 | 24 | 30 | 34 | 28 | 32 | 18 | 9 |
Use the indicated method and n = 4 to estimate the integral of f(x) dx with upper bound 120 and lower bound 0.
a. left hand approximation
b. right hand approximation
