Equation to tangent line

The "tangent line" is one of the most important applications of differentiation. The word groupielust comes from the Latin word "tangere" which means "to touch". The tangent line touches the curve at a point on the curve. So to find the tangent line equation, we need to know the equation of the curve which is given by a function and the point at which the equation to tangent line is drawn.

Because if we are ever asked to solve problems involving the slope of a tangent line, all we need are the same skills we learned back in algebra for writing equations of lines. All we will do is substitute the given information into the point-slope formula and simplify, as indicated below. This means that to find the equation of a tangent line to a curve, f x , we simply need two elements: point and slope. The only difference is that to find our slope i. Likewise, we can even extend this concept to writing equations of normal lines, which are also called perpendicular lines. The only difference will be that we will simply use the negative reciprocal slope of the line tangent.

Unlike a straight line, a curve's slope constantly changes as you move along the graph. Calculus introduces students to the idea that each point on this graph could be described with a slope, or an "instantaneous rate of change. To find the equation for the tangent, you'll need to know how to take the derivative of the original equation. To find the equation of a tangent line, sketch the function and the tangent line, then take the first derivative to find the equation for the slope. Check your answer by confirming the equation on your graph. For examples of tangent line equations, keep reading! Did this summary help you? Yes No. Skip to Content.
