Calculus 3.2

1
product rule
Notice that this is not just the product of two
derivatives.
This is sometimes memorized as
2
quotient rule
or
3
Higher Order Derivatives
(y double prime)
We will learn later what these higher order
derivatives are used for.

5
Consider the function
We could make a graph of the slope
Now we connect the dots!
The resulting curve is a cosine curve.
6
We can do the same thing for
The resulting curve is a sine curve that has been
reflected about the x-axis.
7
We can find the derivative of tangent x by using
the quotient rule.
8
Derivatives of the remaining trig functions can
be determined the same way.
