**Key Ideas about Derivatives (3/20/09)**

The definition and meaning: f ‘ (x) = lim h -> 0 (f (x+h ) – f (x)) / h f ‘ (x) is the instantaneous rate of change of the function f at the point (x, f (x)). If f is graphed, f ‘ is the slope of the tangent line to the graph at that point.

2
The Rules The Rules tell us how to take the derivative of combinations of functions. Constant Multiplier Rule Sum and Difference Rule Product Rule Quotient Rule Chain Rule

3
The Facts The Facts tell us how to take the derivative for different classes of common functions. d/dx ( x r ) = r x r – 1 (r any constant) d/dx ( a x ) = a x ln(a) (a constant > 0) In particular, d/dx ( e x ) = e x d/dx ( loga (x ) = 1 / (x ln(a)) In particular, d/dx ( ln (x) ) = 1 / x

4
**The Facts (Continued) d/dx (sin(x)) = cos(x) d/dx (cos(x)) = - sin(x)**

d/dx (tan(x)) = sec2(x) d/dx (arcsin(x)) = 1 /(1-x 2) d/dx (arccos(x)) = -1 /(1-x 2) d/dx (arctan(x)) = 1 / (1+x 2) Etc.
