Tangent Definition & Meaning - Merriam-Webster
Webnoun. tan· gent ˈtan-jənt. Synonyms of tangent. 1. : an abrupt change of course : digression. the speaker went off on a tangent. 2. a. : the trigonometric function that for an acute angle is the ratio between the leg opposite to the angle when it is considered part of a right triangle and the leg adjacent.
Tangent - Math.net
WebTangent, written as tan (θ), is one of the six fundamental trigonometric functions. Tangent definition. Tangent, like other trigonometric functions, is typically defined in terms of right triangles and in terms of the unit circle.
Sine, Cosine, Tangent - Math is Fun
WebSine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same. no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side. Example: What is the sine of 35°?
Tangent - Tangent to Circle, Meaning, Properties, Examples
WebThe tangent is a straight line that touches the circle at only one point. It is perpendicular to the radius at the point of tangency. It never enters the circle's interior. The lengths of two tangents to a circle from the same external point are equal.
Tangent - Wikipedia
WebIn 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 | Definition, Formulas, & Facts | Britannica
WebMar 29, 2024 · tangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is tan A = length of side opposite angle A/ length of side adjacent to angle A. The other five trigonometric functions are sine (sin), cosine (cos), secant (sec), cosecant (csc), and cotangent (cot).
Tangent Meaning in Geometry and Trigonometry - BYJU'S
WebIn trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side. In other words, it is the ratio of sine and cosine function of an acute angle such that the value of cosine function should not equal to zero.
Tangent -- from Wolfram MathWorld
Web4 days ago · The tangent function is defined by tanx= (sinx)/ (cosx), (1) where sinx is the sine function and cosx is the cosine function. The notation tgx is sometimes also used (Gradshteyn and Ryzhik 2000, p. xxix).
Tangent and Secant Lines - Math is Fun
WebA tangent line just touches a curve at a point, matching the curve's slope there. (From the Latin tangens "touching", like in the word "tangible".) A secant line intersects two or more points on a curve. (From the Latin secare "cut or sever") They are lines, so extend in both directions infinitely. Circle. On a circle they look like this: Theorems.
Tangent - Interactive Mathematics
WebA tangent in geometry is a line that touches a circle at one point. That point is called the point of tangency. It is also known as a tangent line. A tangent line is always perpendicular to the radius of the circle at the point of tangency. The slope of a tangent line is equal to the reciprocal of the radius of the circle.
