What are graphing and calculus?
Graphing and calculus are branches of mathematics that study how functions behave — graphing visualizes a function's shape, while calculus measures its rate of change and accumulated area. Calc Solver provides graphing and calculus calculators to help solve these problems step by stept.
A derivative measures the slope of a curve at any single point
An integral measures the total area accumulated under a curve
Every calc solver tool shows the full working, not just the plotted result

Graphing & calculus questions, answered
The questions people actually search before reaching for a calculator.
What is a derivative in simple terms?
A derivative measures how fast a function's output changes as its input changes — in other words, the slope of the curve at a specific point.
What is the difference between a derivative and an integral?
A derivative measures the rate of change of a function at a point, while an integral measures the total accumulation, such as the area under a curve, across an interval.
How do you find the limit of a function?
Substitute the value the variable is approaching directly into the function. If that produces an undefined result, use algebraic simplification, factoring, or L'Hopital's Rule.
What does the graph of a function show?
The graph of a function shows every input-output pair as a point on a coordinate plane, letting you see the function's shape, direction, and behavior at a glance.
Do I need to know calculus to use calc solver graphing tools?
No. The Function Grapher works for any equation you enter, and the calculus tools walk through each step, so you can learn the concepts as you go.
