We can calculate the slope of a tangent line using the definition of the derivative of a function f at x = c (provided that limit exists): lim h → 0 f (c + h) − f (c) h. Once we've got the slope, we can find the equation of the line. This article walks through three examples.
Let's explore different ways to find and visualize slopes and intercepts, and how these concepts can help us solve real-world problems. Unit guides are here! Power up your classroom with engaging strategies, tools, and activities from Khan Academy’s learning experts.
Learn how to use the midpoint formula to find the midpoint of a line segment on the coordinate plane, or find the endpoint of a line segment given one point and the midpoint. Created by Sal Khan. Questions Tips & Thanks
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 derivatives quickly.
Uncover the process of calculating the slope of a tangent line at a specific point on a curve using implicit differentiation. We navigate through the steps of finding the derivative, substituting values, and simplifying to reveal the slope at x=1 for the curve x²+(y-x)³=28.
