How am I going to remember all of these? “PSST” I know! What are their co-functions?
EX 1: Find the derivative Product Rule THIS THAT
EX 2: Find the derivative HIGH LOW Quotient Rule
EX 3: Find the derivative REWRITE QUOTIENT RULE
EX 4: Find the f’(x) Can you find y’ without using the quotient rule? Use the Constant Multiple Rule. Find f’(3)

ET 2.3b Area of a circle is Volume of a sphereis Volume of a cylinderis Find A’(r). Find V’(r). Find V’(r). Do you notice anything? Hint: It is so cool you can hardly believe your eyes? Circumference of a circle. Surface Area of a Cylinder Surface Area of a Sphere
You could use the quotient rule and then some trig identities.
You can use some trig identities to avoid the quotient rule.

ET 2.3c Use the quotient rule to prove HIGH LOW Pythagorean Idenity Reciprocal Functions
Velocity: Direction matters! Velocity = Speed? Driving a car: Experiencing differentiation first hand Your speed is the first derivative of your position. Stepping on the accelerator or break is a second derivative of your position. I want to do another problem something like #120
