Derivative tools

From a first derivative to directional change and tangent lines, choose the tool that matches the problem you are actually solving.

Derivative CalculatorDifferentiate a function and compare the exact derivative with the original curve.→Partial Derivative CalculatorDifferentiate a multivariable function while treating the other variables as constants.→Second Derivative CalculatorFind the second derivative to study curvature, acceleration, and changing rates of change.→Nth Derivative CalculatorDifferentiate repeatedly from the first through the tenth derivative.→Implicit Derivative CalculatorFind dy/dx from a relation F(x,y)=0 without first solving explicitly for y.→Derivative at a Point CalculatorEvaluate the exact derivative and decimal slope at a chosen input value.→Directional Derivative CalculatorEvaluate how a multivariable function changes at a point along a direction vector.→Tangent Line CalculatorBuild the exact tangent-line equation from a function and a point on its curve.→Chain Rule CalculatorDifferentiate composite functions and see where the outer and inner derivatives combine.→Product Rule CalculatorDifferentiate a product of functions with a result checked against the full expression.→Quotient Rule CalculatorDifferentiate one function divided by another and simplify the resulting fraction.→

Exact mathematics first

Results stay symbolic whenever possible, with decimal values added only when they are useful.

Frequently asked questions

Are the calculations performed by a real math engine?

Yes. Expressions are validated and processed server-side by a symbolic mathematics engine, then verified when a reliable check is available.

Can every integral be solved in closed form?

No. Some functions have no elementary antiderivative. The calculator reports that limitation instead of inventing a result.
