Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of …

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.

The meaning of TANGENT is an abrupt change of course : digression. How to use tangent in a sentence.

The graph of tangent is periodic, meaning that it repeats itself indefinitely. Unlike sine and cosine however, tangent has asymptotes separating each of its periods.

Jan 2, 2026 · The tangent is one of the six fundamental trigonometric functions in mathematics. In a right triangle, it is the ratio of the length of the side opposite a given angle to the length of the …

Jul 23, 2025 · Tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side to the given angle. We write a tangent function …

This tangent calculator will help you to find the tangent of any angle you want. Just enter the angle in degrees or radians, and the tangent will appear in no time.

Dec 22, 2025 · 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 …

The word "tangent" comes from the Latin "tangere," meaning "to touch." Geometrically, the tangent is a line segment perpendicular to the x-axis, originating at point C and intersecting the …

One of the trigonometry functions. In a right triangle, the tangent of an angle is the opposite side over the adjacent side. For more on this see Trigonometry tangent function.
