On using a secant to differentiate: suppose f(x) is differentiable on the interval [C, C+deltaC]. Graph the function and draw a secant line through the points (C, f(C)) and (C+deltaC, f(C+deltaC)). Consider the slope of this line and take the limit as deltaC approaches zero. Look familiar?
ITS YOUR AVATAR!!!!! Either that or the slope will be null :/
