Define Tangent In Geometry Math
The length of the side opposite the angle divided by the length of the adjacent side.
Define tangent in geometry math. A line that just touches a curve at a point matching the curve s slope there. In a right triangle the tangent of an angle is the opposite side over the adjacent side. The abbreviation is tan. More precisely a straight line is said to be a tangent of a curve y f x at a point x c if the line passes through the point c f c on the curve and.
Below the blue line is a tangent to the circle c. Tangent written as tan θ is one of the six fundamental trigonometric functions. In a right angled triangle the tangent of an angle is. The right angled triangle definition of trigonometric functions is most often how they are introduced followed by their definitions in terms of the unit circle.
The shortest distance between two points is a straight line. For more on this see tangent to a circle. Leibniz defined it as the line through a pair of infinitely close points on the curve. Tangent a straight line or plane that touches a curve or curved surface at a point but does not intersect it at that point straight line a line traced by a point traveling in a constant direction.
In geometry the tangent line or simply tangent to a plane curve at a given point is the straight line that just touches the curve at that point. From the latin tangens touching like in the word tangible at left is a tangent to a general curve. One of the trigonometry functions. Tangent line more.
There are two main ways in which trigonometric functions are typically discussed. In terms of right triangles and in terms of the unit circle. Tangent function more.
