How to Use the Derivative Calculator
Our free derivative calculator computes derivatives of polynomial functions with step-by-step solutions. Enter a polynomial function using the format ax^n + bx + c (e.g., 3x^2 + 2x + 1). The calculator applies the power rule: multiply the coefficient by the power, then subtract 1 from the power, and shows each step.
Example Calculations
- f(x) = 3x² + 2x + 1: Apply power rule to each term: d/dx[3x²] = 6x, d/dx[2x] = 2, d/dx[1] = 0. Result: f'(x) = 6x + 2.
- f(x) = 5x³ - 4x² + 7x - 3: d/dx[5x³] = 15x², d/dx[-4x²] = -8x, d/dx[7x] = 7, d/dx[-3] = 0. Result: f'(x) = 15x² - 8x + 7.
- f(x) = xª - 2x³ + x: d/dx[xª] = 6xª, d/dx[-2x³] = -6x², d/dx[x] = 1. Result: f'(x) = 6xª - 6x² + 1.
Frequently Asked Questions
How do I use the Derivative Calculator?
Enter a function like 3x^2 + 2x + 1 and click calculate. The calculator shows the derivative with step-by-step explanations using the power rule. Simply type your function and the result appears instantly.
What types of functions does it support?
It supports polynomial functions, including terms like ax^n, constants, and sums of terms. It also handles trigonometric functions (sin, cos, tan), exponential functions (e^x), and natural logarithms (ln).
What is the derivative of e^x?
The derivative of e^x is e^x itself. This is a unique property of the exponential function — it is the only function that is its own derivative.
How do I find the derivative of a fraction?
Use the quotient rule: (f/g)' = (f'g - fg') / g². For more complex fractions, our calculator handles this automatically by breaking down each term and applying the appropriate rule.
Does it show step-by-step solutions?
Yes, every calculation includes a step-by-step breakdown showing which derivative rule was applied to each term, making it a great learning tool for calculus students.
