Tangent Line Calculator - Find Tangent at Point - Interactive Online Tool

Tangent Line Calculator

Find the equation of the tangent line at any point

📊About Tangent Lines

Definition: A tangent line touches a curve at exactly one point and has the same slope as the curve at that point.

Formula: For point (x₁, y₁), the tangent line equation is: y - y₁ = m(x - x₁)

Steps:

  1. Find the point on the curve: y₁ = f(x₁)
  2. Find the derivative: f'(x)
  3. Calculate the slope: m = f'(x₁)
  4. Use point-slope form to get the equation
