Wanted: A derivative of derivatives.
(If you can't think of any, treat your wife as such).
PS: Suddenly, the irritating boys who insist on asking what the geometric significance of a second order derivative is, will have a large Gujju woman to contend with.
PPS: Yeah, it's not really funny if you did not learn Calculus in a room which also had Dhyanesh.
PPPS: Since we are in a Dhyanesh mood anyway, if there is a valid fourth order derivative and it turns to out to be 0, can we take that Gujju woman to be at her maxima then?
PPPPS: I know, but did the Tamil hatred for maxi start here?
