i need a real world integral problem .. wa0h

i just registered .. age 75

my problem is that i don't have a problem .. please read on

to take a break from writing software i am trying to write a general audience math book .. my approach is to state a simple real world word problem and then show the type of math you need to solve the problem.

for derivatives i used the problem .. I bought a 40 foot roll of garden fence. I want to build a small rectangular garden that has the largest area possible. What will be the dimensions of the garden

*** i can not find a (simple real world word problem) that needs integral calculus to solve the problem .. everything on the internet starts by giving the equation for the problem .. such as .. A faucet is turned on and water flows out at a rate of f(t)

i am not writing a math text book .. i do not expect the reader to know how to differentiate or integrate .. once i show the reader how to set up the problem i show them how to find a website that will solve the problem.

thanks for your time

Find the area between two curves from x=a to x=b. You write the story behind it.

Because you already know how to code, you are an ideal candidate to join us at this website. We need people to help with real-world questions which can be solved with available Computer Algebra Systems.

Word problems such as this ['has the largest area possible', etc.] are generally derivative problems [find the maximum of f(x)=x(40-x)], not integral problems. The integral problem would be more like, given a garden in that shape, what would be it's area [paraphrasing Jomo, integrate the constant function g(x)=20 from 0 to 20].

EDIT: Changes in text to hopefully make clearer
