Are odd numbers connected to odd functions and even numbers to even functions? This video tries to clarify that connection. It also talks about functions that are both odd and even to give a more intuitive feeling about classifying these...

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.

The foci of an ellipse are explored in this video. First, foci are shown as the two points on the central axis such that the sum of the distance from a point on the ellipse and the foci points is the same as the distance from any point...

In this video, Sal shows again how to write an equation of a conic section in standard form and identify the conic section it represents. This time, his example is of a hyperbola (not centered at the origin), which he also graphs.

Here, parabolas, circles, ellipses, and hyperbolas are introduced by showing a general graph of each. By showing the intersection of a plane and a cone to create the different conic sections, one can see how these curves are related.

In this thought-provoking video, Sal shows how a typical linear scale is different from a logarithmic scale. He plots numbers on both scales and compares them to show why the logarithmic scale is useful. This video gives an intuitive...

Why do people perceive a bigger difference between the numbers one and two than between the numbers 1001 and 1002? In this interesting video, Sal is accompanied by Vi Hart. They talk about how we tend to think according to the...

This short video looks at different points on a coordinate plane and answers a question about whether these points could represent a function. The answer is determined by looking at each point individually to determine whether, given a...

Are odd numbers connected to odd functions and even numbers to even functions? This video tries to clarify that connection. It also discusses functions that are neither odd nor even to help you classify them more intuitively.

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

The foci of an ellipse are explored in this video. First, foci are shown as the two points on the central axis such that the sum of the distance from a point on the ellipse and the foci points is the same as the distance from any point...

In this video, Sal shows again how to write an equation of a conic section in standard form and identify the conic section it represents. This time, his example is of a hyperbola (not centered at the origin), which he also graphs.

This is the last of three well-done videos on identifying and graphing conic sections from an equation. Here, Sal graphs a circle that is not centered at the origin and a parabola that opens downward.

Students take an Algebra II/Trigonometry sample test.  In this Algebra II/Trigonometry sample sample test lesson, students take a sample test for Algebra 2/Trigonometry.  Students solve 39 multiple choice/short answer...

A jam-packed worksheet has all the topics you would teach in an Algebra II class with a variety of question styles. Starting with function notation and ending with geometric sequences, there really is something for everyone. Each...

Scientists require specific chemical solutions for their experiments. In the seventh and final installment in a series that integrates chemistry and algebra II, scholars learn to set up a system of equations to solve the volume of a...

Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...

In this quadratic equations worksheet, students solve 15 quadratic equations.  Students factor, complete the square, and use the quadratic formula to solve quadratic equations.

In this Algebra II review:  exponential functions and logarithms worksheet, students solve 19 problems, including making graphs, simplifying and evaluating.

In this Algebra II worksheet, students match the number to the number set it belongs to. Students are given a list of options such as natural, real, complex, and a number that corresponds to on set of options. There are 6 questions.

A full-length practice test like this one, especially one that includes a number of open response questions, is a phenomenal tool in a class as rigorous as algebra 2. Here the learners can really get that hands-on experience...

In this quadratic functions instructional activity, students use their graphing calculators to solve the 9 problems on the page. The questions ask students to graph functions, compare graphs, find the vertex and axis of symmetry and more.

Learners investigate trigonometric function.  In this Algebra II lesson, learners explore functional notation and transformational graphing of trigonometric functions. 

What makes this resource special? The amazing answer key that comes with worked out solutions and notes for each problem. Practice problems include all topics ranging from linear systems to simplifying exponential expressions. The...
