# What is the derivative of an equation?

## What is the derivative of an equation?

Geometrically, the derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

### What is a partial derivative in math?

partial derivative, In differential calculus, the derivative of a function of several variables with respect to change in just one of its variables. For a three-dimensional surface, two first partial derivatives represent the slope in each of two perpendicular directions.

What is variation of a functional?

A variation of a functional is the small change in a functional’s value due to a small change in the functional’s input. It’s the analogous concept to a differential for regular calculus. We’ve already seen an example of a variation in Equation 5, which is the first variation of the functional F: δF(y,η)=∫δFδy(x)η(x)dx.

Is differentiation a functional?

Derivatives: definitions, notation, and rules A derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slope of the original function y = f (x).

## What do you mean by derivative?

Definition: A derivative is a contract between two parties which derives its value/price from an underlying asset. The most common types of derivatives are futures, options, forwards and swaps. Description: It is a financial instrument which derives its value/price from the underlying assets.

### What is derivative example?

What are Derivative Instruments? A derivative is an instrument whose value is derived from the value of one or more underlying, which can be commodities, precious metals, currency, bonds, stocks, stocks indices, etc. Four most common examples of derivative instruments are Forwards, Futures, Options and Swaps.

What do partial derivatives tell us?

The partial derivative f x ( a , b ) tells us the instantaneous rate of change of with respect to at ( x , y ) = ( a , b ) when is fixed at .

How do you differentiate fxy?

Calculate the derivative of the function f(x,y) with respect to x by determining d/dx (f(x,y)), treating y as if it were a constant. Use the product rule and/or chain rule if necessary. For example, the first partial derivative Fx of the function f(x,y) = 3x^2*y – 2xy is 6xy – 2y.

## What is meant by calculus of variation?

The calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers. Many important problems involve functions of several variables.

### Is calculus and differentiation same?

Differential calculus is the study of the definition, properties, and applications of the derivative of a function. The process of finding the derivative is called differentiation.
