Differentiation RulesThe PRODUCT Rule:
In other words, if y = fg then y’ = fg’ + f’g
If y = fgh then y’ = f’gh + fg’h + fgh’

Differentiation Rules The TRIGONOMIC Functions:
These can all be derived from the quotient rule and the derivatives of sine and cosine.
You should become familiar with these!

ExampleThe TRIGONOMIC Functions:
NOTE: Because of trigonometric identities, the derivative of a trigonometric function can take many forms.
High Order DerivativesJust as a velocity function can be obtained by deriving a
position function, acceleration can be obtained by deriving a velocity function. Another way of saying this is that the acceleration function can be obtained by deriving the position function twice.
