This video covers the differential notation dy/dx and generalizes the rule for finding the derivative of any polynomial. It also extends the notion of the derivatives covered in the Khan Academy videos, "Calculus Derivatives 2Ó and...

Sal continues where he left off with the last video, "Derivatives 1,Ó by looking at the equation y = x^2 and examining the slope of the secant line at a specific point, and again defining the limit as x approaches zero to get the slope...

By defining the formal definition of a derivative, f(x), Sal is able to find the general form of the derivate function for the example f(x) = x2. He continues to stress the importance of an intuitive understanding of derivative functions.

Sal works up an appetite for his Thanksgiving turkey in this video, which takes students through the first five problems of a new set of SAT practice questions from The Official SAT Study Guide. Problems involve algebraic word problems,...

After finishing problem 10 about congruent angles inside a polygon, Sal goes on to solve additional problems involving reciprocals, odd integers, and slopes. Those who have a difficult time moving efficiently through different skill sets...

With pen in hand and diagrams at the ready, Sal demonstrates problem-solving and test-taking skills in this informative video. Problems 7-9 involve inequalities, linear equations, and measuring angles in a right triangle.

Sal's lecture starts where his last one ended - on problem 13 from The Official SAT Study Guide. Starting the problem over to ease understanding, he explains how to find the pattern in a complicated sequence. The following problem...

Clarifying that speed matters more than rigor on the SAT, Sal takes care to show students the most efficient and easiest ways to solve various math problems. Those who get stuck on certain types of problems would benefit from his...

Reviewing the last two problems in the practice SAT (17-18), Sal explains the process behind each problem more thoroughly. This video would be especially helpful for students who experience difficulty in graphing or in accurately reading...

Continuing his SAT review session, Sal explores problems with slopes, linear equations, and congruent angles. He begins problem 10 (geometry) but finishes the problem in the next video.

If your class struggles with graphing inequalities, or if your lecture could use some help from Sal, this video would be a great help. Sal's instruction is measured and patient, and viewers will walk away feeling more confident and...

Finding perimeters and slopes is the focus of this video, which details ways to solve problems 15-17 on the practice SAT. Even students who are confident in their ability to pass the SAT would benefit from this additional review.

You'll want to use the video directly, without waiting. Pupils learn how to identify whether a given relationship represents a direct variation by watching an engaging, informative video. They see how tables, graphs, and equations relate...

Word problems are full of valuable information that can be used to create equations. Take your learners on an adventure and figure out a formula that will represent the cost of a rental car. The video asks questions to help understand...

Given a line on a graph, what's the slope of this line? First, identify two points on the given line. Then, use a formula to find the change in y and then the change in x. This will be represented by rise over run. Watch this video to...

Evaluate the steepness of lines, also known as the slope, by watching this video. A tutor explains what the slope of a line is and compares two different lines to demonstrate slope. A practical introductory video for classes that are...

Given a table of x and y values, is it possible to write a linear equation from this information? There will be several steps involved. First is to use the point-slope formula to find a slope. Then use that slope and one of the ordered...

Two equations. What's the solution to this system? How can you solve it? Can you write the two equations in slope-intercept form? Yes, you can. Now graph each equation. Look, the lines are parallel. What does that mean? That means there...

Locating relative extrema and using them to interpret the behavior of the graph are shown here. This lesson is 3 of 6 in the series titled "Finding Relative Extrema."

Students watch a video about finding the slope of a tangent line to a curve (the derivative).
