Tangent: Learn how to find the tangent

Learn how to find the tangent of a circle, a curve, or an angle using different methods and formulas. Explore the applications of tangent in science and technology with examples and FAQs. In geometry, a tangent is a straight line that touches a curve at a single point. Tangents have many applications in everyday life, from architecture to engineering to physics. We say that a tangent is a line that touches the curve at an external point. What are Tangents? A tangent is a straight line that touches a curve at a single point. The point of intersection is known as the point of tangency. The slope of a tangent line at a given point is equal to the derivative of the curve at that ... Learn what tangent is, how to find it using right triangles or unit circle, and how to use it in trigonometry problems. See examples, tables, and a calculator for tangent of any angle.
