Learn. Vectors are used to represent many things around us: from forces like gravity, acceleration, friction, stress and strain on structures, to computer graphics used in almost all modern-day movies and video games. Vectors are an important concept, not just in math, but in physics, engineering, and computer graphics, so you're likely to see ...These materials enable personalized practice alongside the new Illustrative Mathematics 6th grade curriculum. They were created by Khan Academy math experts and reviewed for curriculum alignment by experts at both Illustrative Mathematics and Khan Academy. The derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient rules) that help us find ...

AboutTranscript. Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Example: The mean of 4 , 1 , and 7 is ( 4 + 1 + 7) / 3 = 12 / 3 = 4 . Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere.

At. 5:40. Sal says that you have to do things from left to right when you have multiple operations at the same level. At this point in the video, the problem is: 10 x 4 / 2 - 5 x 6. Sal solves left to right: 40 / 2 - 5 x 6 = 20 - 30 = -10. But if I don't do it in the same order I get the same answer: 10 x 2 - 5 x 6 = 20 - 30 = -10.
