## Derivative Calculator With Steps

Derivative calculator is used to find the derivative of a given function with respect to the independent variable. This differentiation calculator can perform explicit differentiation with just one click.

## Derivative – Definition

Let** f(x)** be a function whose domain contains an open interval at some point

*The function*

**x**._{0}**is said to be differentiable at**

*f(x)**and the derivative of*

**x**,_{0}**at**

*f(x)***is given by:**

*x*_{0}In other words, the **derivative **measures the sensitivity to a change in the function value with respect to a change in its argument. The reverse function of the **derivative **is known as the antiderivative.

**Rules of Derivative**

Here are some rules of differentiation:

Rule name | f(x) | f'(x) |

Constant | (c) | 0 |

Sum | f(x) + h(x) | f'(x) + h'(x) |

Difference | f(x) - h(x) | f'(x) - h'(x) |

Constant Multiple | f(cx) | c * f'(x) |

Product | f(x) * h(x) | f'(x) h(x) + h'(x) f(x) |

Quotient | f(x) / h(x) | 1/h^{2}(x)[f'(x) h(x) - h'(x) f(x)] |

Power | x^{n} | n x^{n-1} |

**Exponential Rules**

The exponential rules of differentiation are used for calculating the derivative of exponential functions. The general expressions are:

f(x) | f'(x) |

a^{x} | ln(a) a^{x} |

e^{x} | e^{x} |

**Logarithmic Rules**

f(x) | f'(x) |

log_{a}(x) | 1/xln(a) |

ln|x| | 1/x |

**Trigonometric Rules**

f(x) | f'(x) |

cos(x) | -sin(x) |

sin(x) | cos(x) |

tan(x) | sec^{2}(x) |

sec(x) | sec(x)tan(x) |

csc(x) | -csc(x)cot(x) |

cot(x) | -csc^{2}(x) |

You can take assistance from the above differentiate calculator to solve differentiation problems according to the above-discussed rules.

## How to find derivatives using rules?

Use our derivative calculator with steps to differentiate the functions according to the rules. Here is a manual example for differentiating a function using rules.

**Example**

Find the derivative of the given function with respect to "**u**".

$$f\left(u\right)=\frac{u}{\left(u^2+1\right)}$$

**Solution**

**Step 1: **Apply **d/du** to the given function.

$$\frac{d}{du}\left[f\left(u\right)\right]=\frac{d}{du}\left[\frac{u}{\left(u^2+1\right)}\right]$$

**Step 2: **Use the quotient rule to differentiate the above expression.

$$=\frac{\left[\left(u^2+1\right)\:\frac{d}{du}\left(u\right)-u\:\frac{d}{du}\left(u^2+1\right)\right]}{\left(u^2+1\right)^2}$$ ... (1)

**Step 3: **Find derivatives

$$\frac{d}{du}\left(u\right)=1$$

$$\frac{d}{du}\left(u^2+1\right)=\frac{d}{du}\left(u^2\right)+\frac{d}{du}\left(1\right)$$ by sum rule

$$\frac{d}{du}\left(u^2+1\right)=2u+0=2u$$

**Step 4:** Now substitute the above results in (1).

$$=\frac{\left[\left(u^2+1\right)\left(1\right)-u\left(2u\right)\right]}{\left(u^2+1\right)^2}$$

$$=\frac{\left[u^2+1-2u^2\right]}{\left(u^2+1\right)^2}$$

$$=\frac{\left[1-u^2\right]}{\left(u^2+1\right)^2}$$

Hence,

**$$\frac{d}{du}\left[\frac{u}{\left(u^2+1\right)}\right]=\frac{\left[1-u^2\right]}{\left(u^2+1\right)^2}$$**
