Derivatives Example: f(x)=√x

Help learners discover the unique characteristics of the tangent function. Working in teams, pupils create tables of values for different intervals of the tangent function. Through teamwork, they discover the periodicity, frequency, and...

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of the...

Using a specific example, Sal shows how to find the equation of a tangent line to a given function at a specific point. Specifically, he solves the problem of finding the tangent line to the function f(x) = xex at x = 1. This problem...

We look at several different examples of functions and see what their domain is. Sal writes the domain in a set notion and shows how different functions can have different input values that cause them to be undefined.

Function, function, what is your notation. Introduce your class to function notation with a video that shows examples of how to evaluate functions at numerical values along with algebraic values. The last example shows pupils how they...

Viewers learn how to find the average of a variable density with a video made for AP Calculus. The presenter applies the formula to find the average value of a function with an example that provides a density function for a rod. The...

Numbers are even and odd, but did you know functions can be too? The lesson shows the process of determining an even or odd function algebraically. It uses polynomial examples and shows an example of each type. 

This time, try graphing three segments. Another Mathispower4u Algebra I Video provides an additional example on graphing a piecewise function. Pupils observe how to graph a function that is made from two constant functions and one linear...

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function, demonstrated in...

How far is that boat from the lighthouse? Scholars create diagrams to represent a scenario given the angle of depreciation from a lighthouse to a boat. Learners apply the basic trigonometric functions to find various distances stemming...
