Differentiate The Following Function Calculator
Differentiation is a fundamental concept in calculus that allows us to find the rate at which a function changes as its input changes. This calculator helps you compute derivatives of functions quickly and accurately.
What is Differentiation?
The derivative of a function measures how a function changes as its input changes. It represents the slope of the tangent line to the function's curve at any given point. Differentiation is essential in physics, engineering, economics, and many other fields.
If y = f(x), then the derivative of y with respect to x is written as dy/dx or f'(x).
Differentiation helps us answer questions like:
- How fast is something accelerating?
- What is the marginal cost of producing one more unit?
- How does temperature change with altitude?
Basic Differentiation Rules
Here are some fundamental rules for differentiation:
Power Rule
If f(x) = xⁿ, then f'(x) = n·xⁿ⁻¹
Example: The derivative of x³ is 3x².
Constant Rule
If f(x) = c (where c is a constant), then f'(x) = 0
Sum/Difference Rule
If f(x) = g(x) ± h(x), then f'(x) = g'(x) ± h'(x)
Product Rule
If f(x) = g(x)·h(x), then f'(x) = g'(x)·h(x) + g(x)·h'(x)
Quotient Rule
If f(x) = g(x)/h(x), then f'(x) = [g'(x)·h(x) - g(x)·h'(x)] / [h(x)]²
Chain Rule
If f(x) = g(h(x)), then f'(x) = g'(h(x))·h'(x)

Worked Examples
Example 1: Linear Function
Find the derivative of f(x) = 3x + 2.
f'(x) = d/dx(3x) + d/dx(2) = 3 + 0 = 3
Example 2: Quadratic Function
Find the derivative of f(x) = x² + 5x - 3.
f'(x) = d/dx(x²) + d/dx(5x) - d/dx(3) = 2x + 5 - 0 = 2x + 5
Example 3: Product of Functions
Find the derivative of f(x) = x·sin(x).
f'(x) = d/dx(x)·sin(x) + x·d/dx(sin(x)) = sin(x) + x·cos(x)
FAQ
What is the difference between differentiation and integration?
Differentiation finds the rate of change of a function, while integration finds the area under a curve or the accumulation of quantities.
Can I differentiate functions with multiple variables?
Yes, but this calculator focuses on single-variable functions. For multivariate functions, you would need partial derivatives.
What if my function has a square root?
Use the chain rule. For example, d/dx(√x) = d/dx(x¹/²) = (1/2)x⁻¹/² = 1/(2√x).
How accurate are the results from this calculator?
This calculator provides exact symbolic derivatives when possible. For numerical approximations, results are accurate to 10 decimal places.
