The Product Rule Complete the warm-up on your notesheet
Objective • To use the product rule for differentiation. • TS: Making decisions after reflection and review
The Product Rule Good News: Right now you can find the derivative of functions like … A number multiplied by a variable raised to a power. Bad News: The Power Rule doesn’t work for a lot of derivatives.
The Product Rule This function consists of two separate pieces multiplied together
The Product Rule What is the derivative of this function?
The Product Rule Take each derivative NO! Does ?
The Product Rule The derivative of a product is not equal to the product of the derivatives.
The Product Rule • The derivative of a product must by calculated using the product rule:
The Product Rule 1. Imagine that the function is actually broken into 2 pieces.
The Product Rule 2. Leave first piece alone and derive second piece.
The Product Rule 3. Add: Leave second piece alone and derive first piece.
The Product Rule This is the derivative!
Conclusion • Remember: The derivative of a product is the first times the derivative of the second plus the second times the derivative of the first.
