how to find derivative For a polynomial like this the derivative of the function is equal to the derivative of each term individually then added together The derivative of x 2 is 2x The derivative of 2x is 2 The derivative of any constant number such as 4 is 0 Put these together and the derivative of this function is 2x 2
Learn about a bunch of very useful rules like the power product and quotient rules that help us find derivatives quickly The derivative of a function describes the function s instantaneous rate of change at a certain point F x lim x 0 f x x f x x The derivative of f equals the limit as x goes to zero of f x x f x over x Or sometimes the derivative is written like this explained on Derivatives as dy dx dy dx f x dx f x dx The process of finding a derivative is called differentiation

Practice 4 questions The big idea of differential calculus is the concept of the derivative which essentially gives us the direction or rate of change of a function at any of its points Learn all about derivatives and how to find them here Find the derivative of g x 3x 2 and compare it to the derivative of f x x 2 Solution We use the power rule directly g x dfrac d dx 3x 2 3 dfrac d dx x 2 3 2x 6x nonumber Since f x x 2 has derivative f x 2x we see that the derivative of g x is 3 times the derivative of
To find the derivative at a given point we simply plug in the x value For example if we want to know the derivative at x 1 we would plug 1 into the derivative to find that f x f 1 2 1 2 2 f x sin x To solve this problem we will use the following trigonometric identities and limits We now know how to find or at least approximate the derivative of a function for any x value this means we can think of the derivative as a function too The inputs are the same x s the output is the value of the derivative at that x value

So it is simply this multiply by power then reduce power by 1 It can also be used in cases like this Example What is d dx 1 x 1 x is also x 1 We can use the Power Rule where n 1 d dx x n nx n 1 d dx x 1 1x 1 1 x 2 1 x2 So we just did this which simplifies to 1 x2 Multiplication by constant Definition Derivative Function Let f be a function The derivative function denoted by f is the function whose domain consists of those values of x such that the following limit exists f x lim h 0f x h f x h A function f x is said to be differentiable at a if f
