Area beneath (or above) curve on graph

B

I was hoping anyone could tell me how, or if excel even can, calculate
the area beneath a curve? I can't find an appropraite funtion to return
this information in the statistics menu, but something tells me that
there should be one. If anyone knows that would be great.

I am actually graphing depth of streams, so my curves are concave-down.
If the function to work out area beneath a curve can be altered to work
out the area *above* one, then the formula would be very useful...and I
would be eternally grateful.

Thanks!

This is quite complex and I don't know if you can do it. sounds like
you need a calculus addin
