Calculus 1 - Section 2.4 Flashcard Product and Quotient Rule

Front

What is the Product Rule in calculus?

Back

The Product Rule states that if you have two functions u(x) and v(x), the derivative of their product is given by: (uv)' = u'v + uv'.

Front

What is the Quotient Rule in calculus?

Back

The Quotient Rule states that if you have two functions u(x) and v(x), the derivative of their quotient is given by: (u/v)' = (u'v - uv') / v^2.

Front

How do you differentiate a function using the Product Rule?

Back

To differentiate a function using the Product Rule, identify the two functions being multiplied, find their derivatives, and apply the formula: (uv)' = u'v + uv'.

Front

How do you differentiate a function using the Quotient Rule?

Back

To differentiate a function using the Quotient Rule, identify the numerator and denominator functions, find their derivatives, and apply the formula: (u/v)' = (u'v - uv') / v^2.

What does it mean for a function to be increasing on an interval?

Back

A function is increasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2, then f(x1) < f(x2).

Front

What does it mean for a function to be decreasing on an interval?

Back

A function is decreasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2, then f(x1) > f(x2).

Front

How can you determine where a function is increasing or decreasing?

Back

To determine where a function is increasing or decreasing, find the derivative of the function, set it to zero to find critical points, and analyze the sign of the derivative in the intervals defined by these points.

Front

What is a critical point in calculus?

Back

A critical point is a point on the graph of a function where the derivative is either zero or undefined, which may indicate a local maximum, minimum, or a point of inflection.

Front

What is the significance of the first derivative test?

Back

The first derivative test is used to determine whether a critical point is a local maximum, local minimum, or neither by analyzing the sign of the derivative before and after the critical point.

Front

What is the second derivative test?

Back

The second derivative test is used to determine the concavity of a function at a critical point. If f''(x) > 0, the function is concave up (local minimum); if f''(x) < 0, the function is concave down (local maximum).
