Learn how to find inverse functions with step-by-step guidance and examples, enhancing your understanding of this fundamental algebra concept.

An inverse square law is characteristic of anything that spreads out in straight lines, without getting lost. Both gravity and electric force have this property.

Sal explains that if f (a)=b, then f ⁻¹ (b)=a, or in other words, the inverse function of f outputs a when its input is b.

Sal explains what inverse functions are. Then he explains how to algebraically find the inverse of a function and looks at the graphical relationship between inverse functions.

Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.

Now, just out of interest, let's graph the inverse function and see how it might relate to this one right over here. So if you look at it, it actually looks fairly identical.

Sal is differentiating the inverse sine function, written as sin⁻¹ (x), which is not the same as (sin x)^-1. That’s why you're getting a different result — you're just solving a different problem.

Learn how to find the inverse of a function and how to graph it in this video. The inverse function swaps the x and y values of the original function, and the graph of this inverse function is a …

What I want to do is use our technique for finding an inverse of this matrix to essentially find a formula for the inverse of a 2 by 2 matrix. So I want to essentially find a inverse, and I want to …
