Finding the integral of a rational function using linear partial fraction decomposition.

Example justifying use of intermediate value theorem (where function is defined with an equation).

Example justifying use of mean value theorem (where function is defined with a table).

When derivatives are used to describe real-world situations, we need to know how to make sense of them.

Finding the equation of a horizontal tangent to a curve that is defined implicitly as an equation in x and y.

Sometimes we can integrate rational functions by using the method of completing the square in the denominator and then integrating using u-substitution and our knowledge about the derivative of arctan(x).

Given the first derivative of an implicit equation in x and y, evaluate the second derivative at a certain point. Problem taken from the 2015 AP Calculus AB exam.

Using definite integration to find volume of a solid whose base is given as a region between function and whose cross sections are squares.

Given an implicit equation in x and y, finding the expression for the second derivative of y with respect to x.

It can be a bit tricky at first to visualize finding the LCM using prime factorization. Let's look at an interesting way to visualize the HCF and the LCM of two numbers in a diagram. Created by Aanand Srinivas.

The product of the HCF and LCM of two numbers is equal to the product of the two numbers. Let's use this property to solve a few questions. We will prove why this is true in another video. Created by Aanand Srinivas.

Finding the HCF from prime factors can sometimes be hard to imagine. Let's look at an interesting way to visualise finding the HCF of two numbers using prime factorisation. Created by
