# Total Differential Calculator + Online Solver With Free Steps

The **Total Differential Calculator** is an online **free **tool that helps you to calculate the total differential of any given function. It finds the **partial derivatives** for the x and y with respect to z and adds them.

The calculator returns the **total differential** of the function as implicit derivatives of x and y with respect to x, y, and z.

## What Is the Total Differential Calculator?

**The total differential calculator is an online calculator that finds the total differential of a given function with respect to the provided variables.**

**Total Differential** is an effective and helpful term used in **Mathematics**, specifically in Ordinary Differential Equations and calculus. It helps to find and approximate unknown values.

**For example,** if there is a triangle and you only know the length of its hypotenuse and one side. If you wish to find the length of the unknown side of that triangle, then you can use the total differential method to estimate the length of the third side of the triangle.

Usually, you can solve the **total differentials** by hand, but it is sometimes a complex and time-consuming process. The complexity increases as the functions become complicated, and you will have to find the partial derivatives individually.

The process of finding the **derivatives **in itself is a time taking approach. So, in a nutshell, finding **Total Differentials **manually can lead you to many problems.

Therefore, we offer you this simple **Total Difference Calculator** that quickly calculates the Total Differentials for any given function. It gives you multiple differentials for the given function.

## How Does the Total Differential Calculator Work?

The** Total Differential Calculator** works by calculating the total differential of the given function. The total differential is determined by finding the **partial derivatives** of the given function’s terms.

This calculator’s understanding will be clearer when there is knowledge about the following basic concepts.

### What Is Differential Equation?

The differential equation is a mathematical equation with one more term and the derivatives of dependent variables concerning the independent variables. The derivatives can be partial derivatives or ordinary derivatives.

A differential equation basically represents the relationship between the quantity changing continuously concerning the variation in other quantities.

#### What Is a Derivative?

A derivative is the rate of change of a function at a point. Derivative measures the slope of the function. It is one of the fundamentals of calculus that is used in solving problems.

For example,

** f(x) = dy/dx**

Here x is the independent and y is the dependent variable.

### What Are the Total Differentials?

The Total Differential of a function is the sum of all the independent variables with the partial derivatives of all the terms of the function concerning the variable times the total differential of that variable.

#### Formulae for Total Differentials

The formula for total differential depends on the number of variables and what the variables are. Following are examples of some basic formulas:

Function

**f(x,y)**

Total Differential

**df = fxdx + fydy**

Function

**f(x, y, z)**

Total Differential

**df = fxdx + fydy + fzdz**

Function

** f(v, w, x, y, z)**

Total differential

**df = fvdv + fwdw + fxdx + fydy + fzdz**

## Solved Examples

A better way to comprehend the calculator’s functioning is to solve some examples using it and analyze those examples.

A few solved examples are given below that will help you to have a better understanding.

### Example 1

Find the total differential for the following equation:

### Solution

The calculator first calculates the partial derivative of x w.r.t z as:

**∂x(y, z)/∂z = 1/2x**

Now, it calculates the partial derivative of x w.r.t y

**∂x(y, z)/∂y = -y/x**

Now, it calculator partial derivative of y w.r.t z

**∂y(x, z)/∂z = 1/2y**

It calculates the partial derivative of y w.r.t x

**∂y(x, z)/∂x = -x/y**

Now, it calculates the partial derivative of z w.r.t y

**∂z(x, y)/∂y = 2y**

Finally, it calculates the partial derivative of z w.r.t x

**∂z(x, y)/∂x = 2x**
