how to find the 2nd derivative of a function Free secondorder derivative calculator second order differentiation solver step by step
We dive into the fascinating realm of second derivatives starting with the function y 6 x Together we apply the power rule to find the first derivative then repeat the process to reveal the second derivative This journey illuminates how we can use mathematical tools to uncover deeper layers of a function s behavior By taking the derivative of the derivative of a function f text we arrive at the second derivative f text The second derivative measures the instantaneous rate of change of the first derivative The sign of the second derivative tells us whether the slope of the tangent line to f is increasing or decreasing

The second derivative of a function is simply the derivative of the function s derivative Let s consider for example the function f x x 3 2 x 2 Its first derivative is f x 3 x 2 4 x To find its second derivative f we need to differentiate f Second Derivative Let y f x The second derivative of f is the derivative of y f x Using prime notation this is f x or y You can read this aloud as f double prime of x or y double prime Using Leibniz notation the second derivative is written frac d 2y dx 2 or frac d 2f dx
Step 1 Finding the second derivative To find the inflection points of f we need to use f f x 5 x 4 20 3 x 3 f x 20 x 3 20 x 2 20 x 2 x 1 Step 2 Finding all candidates Similar to critical points these are points where It helps you practice by showing you the full working step by step differentiation The Derivative Calculator supports computing first second fifth derivatives as well as differentiating functions with many variables partial derivatives implicit differentiation and calculating roots zeros You can also check your answers

Define the derivative function of a given function Graph a derivative function from the graph of a given function State the connection between derivatives and continuity Describe three conditions for when a function does not have a derivative Explain the meaning of a higher order derivative The second derivative is what you get when you differentiate the derivative Remember that the derivative of y with respect to x is written dy dx The second derivative is written d 2 y dx 2 pronounced dee two y by d x squared Image Stationary Points
The most common ways are df dx d f d x and f x f x When a derivative is taken n n times the notation dnf dxn d n f d x n or f n x f n x is used These are called higher order derivatives Note for second order derivatives the notation f x f x is often used Possible Answers Correct answer Explanation To take the derivative of a function we ll need to apply the power rule to a term with a coefficient and an exponent Applying this rule to each term in the function we start by taking the first derivative Finally we take the second derivative Report an Error
