what does 'd' stand for?

It stands for "derivative"; think of it as difference for a small change (strictly speaking, infinitesimal change). --Sabik 03:20, 28 July 2007 (UTC)

i dont agree with the assertion "When marginal revenue is equal to zero, price elasticity of demand is equal to 1." if revenue equals price times quantity sold, and price elasticity of demand is equal to the percentage change in quantity demanded divided by the percentage change in price, then for price elasticity to be plus one, a positive increase in price would increase demand, and this implies an increase in revenue. —Preceding unsigned comment added by 138.38.217.40 (talk) 16:21, 13 October 2007 (UTC)
