*f*is monotonic on a closed interval, then

*f*is integrable on the closed interval.

Or basically if it is increasing or decreasing on the interval it is integrable on that interval

This makes sense, however this theorem seems to obvious because obviously if a function is countinuous on a closed interval it will be integrable on that interval whether or not its increasing or not...

So my question is... what is a non monotonic function..? would that be a function with discountinuities?
