二次導関数計算機

ax^nの二次導関数を計算します。

はじめに

Second Derivative Calculator — Compute the second derivative of ax^n. Enter Coefficient a, Exponent n, x to get an instant, accurate result.

計算式

Power rule applied twice: d²/dx²[a×xⁿ] = a×n×(n−1)×x^(n−2), evaluated exactly at the given x.

ステップごとの説明

  1. Enter the Coefficient a.
  2. Enter the Exponent n.
  3. Enter the x.
  4. Click Calculate to see your result instantly.

実例

Example: With Coefficient a = 2, Exponent n = 3, x = 2, the Second Derivative Calculator gives Coefficient: 12, Exponent: 1, Value At X: 24.

よくある質問

What does the second derivative tell you?
It describes the rate of change of the slope — often interpreted as concavity or acceleration.
Is this exact or numeric?
Exact, applying the power rule symbolically twice before evaluating at x.
What inputs does the Second Derivative Calculator need?
You'll need to provide: Coefficient a, Exponent n, x. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Second Derivative Calculator?
The Second Derivative Calculator applies the formula exactly as calculated — Power rule applied twice: d²/dx²[a×xⁿ] = a×n×(n−1)×x^(n−2), evaluated exactly at the given x. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Second Derivative Calculator free to use?
Yes, the Second Derivative Calculator is completely free, requires no signup, and runs instantly in your browser.

二次導関数計算機について

The Second Derivative Calculator uses a real, verifiable formula — Power rule applied twice: d²/dx²[a×xⁿ] = a×n×(n−1)×x^(n−2), evaluated exactly at the given x. — so results are accurate every time, not an approximation.
