How do I enter the function?

Write the polynomial coefficients from the highest degree, comma separated - for 3x^3 - 5x + 2 write 3, 0, -5, 2.

Does it show the steps?

Yes - the power rule is applied to each term and the steps are shown.

Yes, there is an optional field to compute the derivative at a given x.

Write the polynomial coefficients starting from the highest degree, separated by commas. For example for 3x³ − 5x + 2 write: 3, 0, -5, 2.

Coefficients (comma separated)

Derivative at x (optional)

Write coefficients in decreasing order of degree (the highest power of x first).
Write 0 for any missing power in between.
The power rule (d/dx xⁿ = n xⁿ⁻¹) is applied to each term and the steps are shown.

Note: This tool only works for polynomials and uses the power rule. Trig, log and exponential functions are not supported.

Write coefficients in order from the highest power of x down to the constant term.
Put 0 for any missing power — for x³ + 2x write 1, 0, 2, 0.
The steps show the power rule on each term, useful for checking homework.
