Derivative Calculatorとは？
Compute symbolic derivatives of functions in one variable with step-by-step differentiation rules. Enter expressions like x^3 + 2x^2 - 5x + 1, sin(x), or x^2*sin(x). The calculator applies sum, product, quotient, power, and chain rules for sin, cos, tan, ln, log, sqrt, exp, and abs. Choose 1st or 2nd derivative. Free, private, and instant in your browser.
Derivative Calculatorの使い方
- Enter a function of your variable (e.g. x^3 + 2*x^2 - 5*x + 1).
- Set the variable letter if it is not x.
- Choose 1st or 2nd derivative.
- Read the symbolic result and differentiation steps.
- Copy the result for homework or notes.
よくある使用例
- Checking calculus homework derivatives
- Finding the slope function f'(x) from a polynomial
- Practicing product and chain rule on sin(x^2) or x^2*sin(x)
よくある質問
- What functions are supported?
- Polynomials, sin, cos, tan, ln, log (base 10), sqrt, exp, abs, constants pi and e, and combinations with +, −, ×, ÷, and powers.
- How do I write multiplication?
- Use * explicitly (2*x) or write 2x — implicit multiplication is supported.
- Can I find second derivatives?
- Yes. Switch to 2nd derivative mode to differentiate the result again symbolically.
- Is the output simplified?
- Basic simplification is applied (combining constants, removing +0 and *1). Results may still be expanded rather than factored.
