![]() SolutionĪpply the derivative power rule here by multiplying the exponent with the constant and subtracting 1 from the power of the variable. We can apply the power rule even if the exponent is a fraction or a negative number.įind derivative of the function. The general notation of the derivative power rule is given below: In this article, we will discuss the functional power rule of the derivative in detail along with relevant examples. One of the rules is functional power rule. We generally denote the derivative of the function in the following way:įrom the above notation, we can say that the derivative of the function is rate of change of y with respect to the variable x. Differentiation and integration, both are important concepts in calculus. The inverse of differentiation is integration. Differential calculus is a sub field of calculus. When we differentiate a function, then it means that we are finding its slope. The process of finding the derivative of a function is known as differentiation. "An instantaneous rate of change of the function at any given point is known as derivative of that function". We also look at the concept of marginal change from economics, and discuss acceleration and other higher-order derivatives.Derivatives are one of the basic building blocks of calculus. approximate derivatives can be obtained from graphs and tables. Estimating partial derivatives from tables In the next example we estimate partial derivatives of a function of two variables whose values are given in a table by employing procedures that we used Section 2.5 to estimate derivatives of. The slope of this tangent line is the y-derivative (4) of g at (2,1). 1 General Rules 2 Powers and Polynomials with its tangent line at y = 1.
