Tangent
The tangent is a straight line that touches a curve or circle at a single point. It is a local approximation of the curve or circle at that point. The tangent is often used in calculus to find derivatives and construct tangent planes.
The pronunciation of "tangent" is /ˈtændʒənt/.
Usage
In mathematics, the tangent is a fundamental concept in calculus and geometry. It is used to find the slope of a curve at a single point and to determine the equation of a tangent line. The tangent is also used in trigonometry to find the ratio of two sides of a right triangle.
Example Sentences
- At the point of tangency, the tangent is perpendicular to the radius of the circle.
- The tangent to the curve at the point (2,4) is y = 3x - 2.
- The tangent of 45 degrees is equal to 1.
Synonyms
- Secant - A line that intersects a curve at two or more points.
- Gradient - The slope of a line or the rate of change of a function.
- Slope - The steepness of a line or a surface.
Antonyms
- Normal - A line that is perpendicular to a curve or surface at a given point.
- Curved - Not straight.
- Concave - Curving inward.
The word "tangent" has a high frequency of use in mathematics and is less common in everyday language.
