Frequently Asked Questions
Common questions about the Derivative Calculator.
How does the derivative calculator work?
Enter a function of x, choose the derivative order, and it differentiates instantly, showing every rule applied along the way.
Is it free?
Completely free, no sign-up, downloads, or limits.
Does it show the steps, not just the answer?
Yes, each differentiation rule (power, chain, product, quotient) is shown explicitly in sequence.
Can it compute higher-order derivatives?
Yes, choose 1st through 4th derivative from the order selector.
What functions are supported?
Polynomials, trigonometric, exponential, logarithmic, and root functions, plus combinations of them via the chain/product/quotient rules.
Can I evaluate the derivative at a specific point?
Yes, enter a value of x to get the numeric slope of the tangent line at that point.
What happens at points where the function isn't differentiable?
The calculator detects these (e.g. division by zero, invalid domain) and explains why, instead of showing an error or NaN.
Does it simplify the final answer?
Yes, the derivative is simplified and combined into its most readable form.
Is my input stored anywhere?
No; everything runs in your browser and isn't stored or sent anywhere.
Does it work on mobile?
Yes, fully responsive, including the graph and step-by-step panel.
