2022年11月16日 · A tangent line to the function \(f(x)\) at the point \(x = a\) is a line that just touches the graph of the function at the point in question and is “parallel” (in some way) to the graph at that point.
Tangent Line - Equation, Slope, Horizontal | Point of Tangency
The tangent line of a curve at a given point is a line that just touches the curve at that point. Learn how to find the slope and equation of a tangent line when y = f(x), in parametric form and in polar form.
Tangent - Wikipedia
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is, intuitively, the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve.
Tangent Line: What a tangent line is, how to find it, and why it ...
In calculus, the tangent line is used to approximate the behavior of a curve at a certain point. Understanding the tangent line is essential to solving problems related to optimization, velocity, and acceleration.
How to Find the Equation of a Tangent Line – mathsathome.com
A tangent line to a curve is a straight line that just touches the curve at one point. The tangent line has the same gradient as the curve does at this point. The tangent to the curve above is shown in red.

5.1: The Equation of a Tangent Line - Mathematics LibreTexts
2023年6月21日 · Given a simple function \(y=f(x)\) and a point \(x\), be able to find the equation of the tangent line to the graph at that point. Graph both a function and its tangent line using a spreadsheet or your favorite software.
3.1: Tangent Lines - Mathematics LibreTexts
2023年8月29日 · In trigonometry you probably learned about tangent lines to circles, where a tangent line is defined as the unique line that touches the circle at only one point, as in the figure on the right. In this case the tangent line is always on one side of the circle, namely, the exterior of the circle; it does not cut through the interior of the circle.
