Tangents and normals are lines related to curves. A tangent is a line that touches a curve at a specific point without crossing it at that point, and every point on a curve has its tangent . A normal, on the other hand, is a line that is perpendicular to the tangent at the point where the tangent contacts the curve. The tangent formulas are formulas about the tangent function in trigonometry. Understand the tangent formulas with derivation, examples, and FAQs. The tangent function is one of the main six trigonometric functions and is generally written as tan x. It is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled triangle. We have various trigonometric identities and formulas related to the tangent function that can be derived using different formulas. The formula for the period of the tangent function f (x) = a tan (bx), is given by, Period = π/|b|. Tangent function tan x is a periodic ...
