Working a difference quotient involving a square root Suppose f(x) = p x and suppose we want to simplify the differnce quotient f(x+h) f(x) h as much as possible (say, to eliminate the h in the denominator). Substituting the deﬁnition of f into the quotient, we have f(x+h) f(x) h = p

THE DIFFERENCE QUOTIENT
Difference Quotient . James S Jun 2010 r6 The Difference Quotient is an algebraic approach to the . Derivative (dx dy) and is sometimes referred to as the “ Four Step Method. ” It is a way to find the slope of a line tangent to some function . f (x) at some point (x) on the function that is continuous at that (x). The idea of a limit is to get

The difference quotient formula is now stored in table named m. In practise, it is often necessary to use the simplify command to force Maple to simplify the difference quotient. For example, f x dx3 K3 x2 K4 f:= x/x3 K3 x2 K4 Notice that in the previous command, Maple complains about parts of the expression being ambiguous, in this case, f x ...

THE DIFFERENCE QUOTIENT f(xh)f(x) h +− VOCABULARY A quotient is the answer to a division problem. When one writes a fraction, one is really writing a division problem. Think about it. Isn’t 12 4 the same thing as saying 12 divided by 4? Both produce the answer “3”. So when you look at f(xh)f(x) h +−, think of it as a fraction.
