It can also be termed as the slope of a function. Derivative of a function f x wrt to x is represented as. Different syntax of diff method are:. Example 2: Evaluating the derivative of a function at a specified value using subs y,x,k. It returns the double derivative of function f with respect to variable b. In the same way, you can also calculate the k-order derivative of function f using diff f,x,k.

Help Center Help Center. Numerical integration functions can approximate the value of an integral whether or not the functional expression is known:. When you know how to evaluate the function, you can use integral to calculate integrals with specified bounds. To integrate an array of data where the underlying equation is unknown, you can use trapz , which performs trapezoidal integration using the data points to form a series of trapezoids with easily computed areas. For differentiation, you can differentiate an array of data using gradient , which uses a finite difference formula to calculate numerical derivatives. This example shows how to parametrize a curve and compute the arc length using integral. This example shows how to calculate complex line integrals using the 'Waypoints' option of the integral function. This example shows how to use the polyint function to integrate polynomial expressions analytically. This example shows how to integrate a set of discrete velocity data numerically to approximate the distance traveled.
