Question 1

How does the derivative calculator work?

Accepted Answer

Type your function using x as the variable, then press Differentiate. The tool parses your expression into a math tree and applies the differentiation rules (power rule, product rule, quotient rule and chain rule) symbolically, then simplifies the result.

Question 2

What rules of differentiation are supported?

Accepted Answer

The calculator supports the power rule, sum and difference, product rule, quotient rule, chain rule, and derivatives of sin, cos, tan, exp, ln, log, sqrt, asin, acos, atan and more.

Question 3

Can I evaluate the derivative at a point?

Accepted Answer

Yes. After computing the derivative, enter a value of x to instantly evaluate both the original function and its derivative at that point.

Question 4

Does the tool send my function to a server?

Accepted Answer

No. All parsing, differentiation and simplification happens locally in your browser. Nothing is uploaded.
