I've been using excel for some math analysis and came to a stop when I
found that excel did not have an integration function

I'm not asking for anything fancy. Numerical integration using the
trapezoidal rule would do.

I have some foggy ideas how to go about this. Here goes.
Write the integration function in qbasic(a primitive language but still
good enough) then tell qbasic to make a file containing the data that is
needed. Then excel SOMEHOW looks at this file and pastes the data into
the cells.

Is there a better way?? or how does one implement the above method?
