Introduction to Tangent Line Calculator

The tangent line slope calculator is an advanced online tool that can assist you in calculating tangent lines. It uses the tangent line's slope to calculate the tangent line's equation. It needs just an input value to provide you with a tangent line. It allows you to save your time and energy from doing manual calculations.

The tangent line equation calculator is made by using the concept of derivatives. Because it uses a derivative formula to calculate the slope of the tangent line that gives the tangent line equation. Here, we introduce this tool so that you can easily calculate the equation of the tangent line without any manual calculations.

Formula used by Horizontal Tangent Line Calculator

The tangent line is a line that is drawn on the curve at the point of change. It represents the instantaneous rate of change at that point. The slope of the curve line at that point is calculated using derivatives. This slope is then used to calculate the equation of a tangent line. The equation of the tangent line calculator does these steps quickly to provide results within a few seconds.

The formula that this tool uses is expressed as;

$y-y_1=m(x-x_1)$

It is also written as,

$y=m(x-x_1)+y_1$

It is also known as the standard or slope-intercept form of the tangent line. Where (x1,y1) is the coordinate points on the curve. You can also use the normal line calculator, which provides you with the tangent line equation and the normal line equation.

The tangent line finder uses the above formula to provide you with the equation of a tangent line easily and quickly.

Tangent Line example

Let's calculate the slope of the line tangent at point $x_0=3$ to the curve $y=3x^2-5x+7$.

First we need to calculate the value of y at x0.

$y(x_0)=y(3)=3(3)^2-5(3)+7=$

$y(3)=3(9)-15+7=27-8=19$

We need to calculate the derivative of the given curve, which can be used to find the slope of the tangent line. So,

$y'(x)=\frac{d}{dx}(3x^2-5x+7)$

$y'(x)=6x-5$

The slope $m$ of the tangent line can be obtained by finding $y'(x_0)$. Therefore, substituting $x_0=3$ and,

$m=y'(3)=6(3)-5=18-5=13$

The equation of tangent line formula is,

$y=m(x-x_0)+y(x_0)$

Substituting the values of $m$ and $y(x_0)$ we get,

$y=13(x-3)+19$

Or,

$y=13x-20$
