Enter f(x)

Evaluate at x =

The F Prime Calculator is an advanced online calculus tool designed to help users quickly find the derivative of a function, commonly written as f′(x) or “f prime of x.” In mathematics, differentiation is a core concept used to measure how a function changes at any given point. However, manual differentiation can become extremely complex when dealing with polynomials, trigonometric expressions, exponential functions, or combinations of multiple functions.

This is where the F Prime Calculator becomes essential. It simplifies the entire process of differentiation by instantly computing derivatives and presenting accurate results. Whether you are a student, teacher, engineer, or researcher, this tool helps you save time and avoid calculation errors.

The main purpose of the F Prime Calculator is to transform a mathematical function into its derivative form using standardized calculus rules such as the power rule, product rule, quotient rule, and chain rule.

What is F Prime (f′)?

In calculus, f′(x) represents the derivative of a function f(x). It shows:

The rate of change of a function
The slope of a curve at a specific point
How a function behaves as input values change

For example:

If f(x) = x², then f′(x) = 2x
If f(x) = sin(x), then f′(x) = cos(x)

The F Prime Calculator automates this entire process without requiring manual derivation.

Inputs Required in F Prime Calculator

To properly use the calculator, the following inputs are essential:

1. Function f(x)

This is the mathematical expression you want to differentiate.

Examples:

x² + 3x + 5
sin(x) + cos(x)
e^x
(x² + 1)(x + 2)

2. Variable of differentiation

Usually:

x (default variable)
But sometimes:
t, y, or other variables in physics/engineering problems

3. (Optional) Point value

Some versions of the tool also allow:

Finding derivative at a specific point x = a

Formula and Logic Behind F Prime Calculation

The calculator uses fundamental calculus rules:

Power Rule

$\frac{d}{dx}(x^n)=n x^{n-1}$ dxd(xn)=nxn−1

Constant Rule

$\frac{d}{dx}(c)=0$ dxd(c)=0

Sum Rule

$\frac{d}{dx}(f(x)+g(x))=f'(x)+g'(x)$ dxd(f(x)+g(x))=f′(x)+g′(x)

Product Rule

$\frac{d}{dx}(f(x)g(x))=f'(x)g(x)+f(x)g'(x)$ dxd(f(x)g(x))=f′(x)g(x)+f(x)g′(x)

Chain Rule

$\frac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x)$ dxdf(g(x))=f′(g(x))⋅g′(x)

The F Prime Calculator automatically applies these rules in correct order.
