Hello i have a quiz on monday and i really need to understand these concepts plzzz.

1.)Know the Product, Quotient, and Chain rules for differentiation. They will not be provided.

2) Know the basic differentiation rules from 2.2 including, but not exclusive to, the Power Rule and the derivatives for sin(x), cos(x), tan(x), and sec(x). They will not be provided.

3) Know how to find the equation of a tangent line at a given point.

4) Know how to find the location of horizontal tangents (i.e. the points where the derivative is equal to 0).

5) Know how to find the second derivative and evaluate it at a given point.

6) Know the Pythagorean Trig Identity and the Double Angle Trig Identities for sin(2x) and cos(2x). You will need to apply one or more of these identities on the quiz. They will not be provided.
