### What do partial derivatives tell us?

Partial derivatives tell you how a multivariable function changes as you tweak just one of the variables in its input. Created by Grant Sanderson.

**How do you know if a derivative is correct?**

Pick a number of points on x-axis and check them like that. Take into account that the approximation error needs to be compared to the value of your derivative at that point. For any specific derivative, you can ask a computer to check your result, as several other answers suggest.

**Can Wolfram Alpha solve PDEs?**

The Wolfram Language’s differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without the need for preprocessing by the user. One such class is partial differential equations (PDEs).

## What does implicit differentiation tell us?

The technique of implicit differentiation allows you to find the derivative of y with respect to x without having to solve the given equation for y. The chain rule must be used whenever the function y is being differentiated because of our assumption that y may be expressed as a function of x.

### What is the derivative rule for a single variable?

Read this rule as: if y is equal to the sum of two terms or functions, both of which depend upon x, then the function of the slope is equal to the sum of the derivatives of the two terms. If the total function is f minus g, then the derivative is the derivative of the f term minus the derivative of the g term.

**What are partial derivatives used for in real life?**

Partial differential equations are used to mathematically formulate, and thus aid the solution of, physical and other problems involving functions of several variables, such as the propagation of heat or sound, fluid flow, elasticity, electrostatics, electrodynamics, etc.

**What does it mean when the partial derivative is negative?**

The derivative in the x direction is negative and has a large magnitude. On the other hand, if we travel in the positive y direction, the elevation changes slowly. We can travel in any direction, not only parallel to the x and y axes, and the derivative depends on the direction.

## What is the integral of 2x?

You already know the derivative of x2 is 2x, so the integral of 2x is x2.
