Derivative Integral Calculator
This derivative integral calculator helps you compute derivatives and integrals of mathematical functions. Whether you're a student studying calculus or a professional working with physics and engineering problems, this tool provides accurate results and explanations for your calculations.
What is a Derivative Integral Calculator?
Derivatives and integrals are fundamental concepts in calculus that describe rates of change and accumulation of quantities, respectively. A derivative integral calculator automates these calculations, saving time and reducing errors in manual computations.
Derivatives measure how a function changes as its input changes. For example, the derivative of position with respect to time gives velocity. Integrals, on the other hand, find the accumulated value of a function over an interval, such as the total distance traveled given velocity over time.
This calculator supports basic functions including polynomials, trigonometric functions, exponential functions, and logarithmic functions. For more complex functions, you may need to use symbolic computation software.

Using the derivative integral calculator is straightforward:
- Select whether you want to calculate a derivative or integral.
- Enter the function you want to differentiate or integrate.
- Specify the variable with respect to which you're differentiating or integrating.
- Click "Calculate" to get the result.
The calculator will display the result in both symbolic and numerical forms when possible, along with a step-by-step explanation of the calculation process.
Formulas and Methods
The calculator uses standard calculus formulas for differentiation and integration:
Differentiation Formulas
For a function f(x), the derivative f'(x) is calculated using basic differentiation rules:
- Power rule: d/dx [x^n] = n*x^(n-1)
- Sum rule: d/dx [f(x) + g(x)] = f'(x) + g'(x)
- Product rule: d/dx [f(x)*g(x)] = f'(x)*g(x) + f(x)*g'(x)
- Quotient rule: d/dx [f(x)/g(x)] = [f'(x)*g(x) - f(x)*g'(x)] / [g(x)]^2
- Chain rule: d/dx [f(g(x))] = f'(g(x))*g'(x)
Integration Formulas
For a function f(x), the integral ∫f(x)dx is calculated using basic integration rules:
- Power rule: ∫x^n dx = (x^(n+1)/(n+1)) + C (n ≠ -1)
- Sum rule: ∫[f(x) + g(x)]dx = ∫f(x)dx + ∫g(x)dx
- Constant multiple rule: ∫k*f(x)dx = k*∫f(x)dx
- Substitution rule: ∫f(g(x))*g'(x)dx = ∫f(u)du where u = g(x)
The calculator implements these formulas to provide accurate results for a wide range of functions.
Worked Examples
Example 1: Differentiating a Polynomial
Let's find the derivative of f(x) = 3x^4 - 2x^2 + 5x + 1 with respect to x.
Using the power rule:
f'(x) = d/dx [3x^4] - d/dx [2x^2] + d/dx [5x] + d/dx [1]
= 3*4x^(4-1) - 2*2x^(2-1) + 5*1x^(1-1) + 0
= 12x^3 - 4x + 5
Example 2: Integrating a Trigonometric Function
Let's find the integral of f(x) = sin(x) with respect to x.
The integral of sin(x) is -cos(x) + C:
∫sin(x)dx = -cos(x) + C
These examples demonstrate how the calculator applies differentiation and integration rules to find solutions.
