Key Formulas Explained

Understanding the key formulas used in calculus can help you appreciate the results provided by the integral derivative calculator.

Derivatives

The derivative of a function f(x) with respect to x is denoted as f'(x) or dy/dx. It represents the rate of change of the function with respect to x.

Power Rule: If f(x) = x^n, then f'(x) = n*x^(n-1)

Exponential Rule: If f(x) = e^x, then f'(x) = e^x

Trigonometric Rules:

d/dx(sin x) = cos x
d/dx(cos x) = -sin x
d/dx(tan x) = sec² x

Integrals

The integral of a function f(x) with respect to x is denoted as ∫f(x)dx. It represents the area under the curve of the function.

Power Rule: ∫x^n dx = (x^(n+1)/(n+1)) + C, where n ≠ -1

Exponential Rule: ∫e^x dx = e^x + C

Trigonometric Rules:

∫sin x dx = -cos x + C
∫cos x dx = sin x + C
∫sec² x dx = tan x + C

Worked Examples

Let's look at some examples to see how the integral derivative calculator works in practice.

Example 1: Derivative of a Polynomial Function

Find the derivative of f(x) = 3x² + 2x + 1.

Solution:

Apply the power rule to each term:

d/dx(3x²) = 6x
d/dx(2x) = 2
d/dx(1) = 0

Combine the results: f'(x) = 6x + 2

Result: The derivative of 3x² + 2x + 1 is 6x + 2.

Example 2: Integral of a Trigonometric Function

Find the integral of f(x) = sin x from 0 to π.

Solution:

Apply the integral rule for sin x:

∫sin x dx = -cos x + C

Evaluate the definite integral:

At x = π: -cos(π) = -(-1) = 1
At x = 0: -cos(0) = -1

Subtract the lower limit from the upper limit: 1 - (-1) = 2

Result: The integral of sin x from 0 to π is 2.
