Summation on HP48G? Message #1 Posted by Ren on 24 Oct 2007, 3:03 p.m.
Hello,
In my Software Testing class, the text said that a graph
with 5 possible paths and up to 18 iterations(loop) could
equal 4.77 Trillion test cases.
Our assignment was to figure out how the author arrived at
that figure.
Well, I didn't get it figured out before the deadline...
but a couple of classmates said it was a Summation problem.
18 on top of the Sigma, 5^i right of the Sigma and
i = 1 on the bottom of the Sigma.
My HP48G has a Sigma (Green shift TAN) but I haven't figured
out how to use it.
Could someone show me how?
Sincerely,
the Klutzy Math Groupie,
Ren
