Find the derivative of the following function with respect to the corresponding independent variable. {eq}y = x \ sin \ x \ cos \ x. {/eq} Some Rules in Finding Derivative Given two functions {eq}f(x) {/eq} and {eq}g(x), {/eq} {e...
Quotient rule, Rule for finding the derivative of a quotient of two functions. If both f and g are differentiable, then so is the quotient f(x)/g(x). In abbreviated notation, it says (f/g)′ = (gf′ −
What does it mean to find the derivative of a function? The derivative of a function is the rate of change of one variable with respect to another. It means that a derivative gives the slope of a function at a single point. What is the derivative of 1? 1, or any number by itself,...
We establish an investigation on a boundary value problem of weighted fractional derivative of one function with respect to another variable order function. It is essential to keep in mind that the symmetry of a transformation for differential equations is connected to local solvability, which is ...
Partial derivative tells us todifferentiatea function partially. It means if we are differentiating partially with respect to one variable, then the remainingvariablesof the function must be treated as constants. What is the Chain Rule of Partial Derivatives?
G = functionalDerivative(f,y) returns the functional derivative δSδy(x) of the functional S[y]=∫baf[x,y(x),y′(x),...] dx with respect to the function y = y(x), where x represents one or more independent variables. The functional derivative relates the change in the functio...
Steps for Interpreting the Derivative of a Function as the Instantaneous Rate of Change Step 1: Identify the independent variable in the function. Step 2: To find the instantaneous rate of change of the function with respect to its independent variable, find...
Since we have two variables, we must treat one as a constant when we take the derivative of the function with respect to the other variable. That means that if we take the derivative with respect to y, then the second variable x is trea...
