How To Find Slope And Equation Of Tangent Line Complete Guide

how to find slope and equation of tangent line. We will also discuss using these derivative formulas to find the tangent line for parametric curves as well as determining where a parametric curve in increasingdecreasing and concave upconcave down. Find the number in front of the x usually written as m to determine slope.

The difference quotient gives the precise slope of the tangent line by sliding the second point closer and closer to 7 9 until its distance from 7 9 is infinitely small. Find the derivative and use it to determine our slope m at the point given Determine the y value of the function at the x value we are given. Fx sqrt x dfrac1sqrt.

The difference quotient gives the precise slope of the tangent line by sliding the second point closer and closer to 7 9 until its distance from 7 9 is infinitely small.

Okay enough of this mumbo jumbo. To find the equation of a line you need a point and a slope. Since a tangent line is of the form y ax b we can now fill in x y and a to determine the value of b. When dealing with a curved line where the slope is changing you cant use the same formula.
