About the Graphing Calculator
Plot the graph of a function, view its derivative and inspect its shape over a range of x-values.
How to use the Graphing Calculator
- Type your Function, for example
x^2orsin(x). - Set the range with From and To, choose the Resolution and tick Show Derivative or Show Grid if you like.
- Press Plot Graph.
Formula and method
The calculator evaluates the function at many x-values across the range and joins the points. The derivative shows the slope of the function at each point.
Tips
- Use ^ for powers, and functions such as sin(x), cos(x), log(x) and sqrt(x).
- Increase the resolution for smoother curves, and adjust the range to zoom in.
