## Numerical Differentiation (as applied to graphing)

See *numerical differentiation* in the existing Tech Notes file.

In graphing the *d/dx* function can be used to graph the derivative of

a given function.

Enter your function as Y_{1}, and its derivative as Y_{2} as shown below:

Press [GRAPH] to view the graph of the function and its derivative.

Press [TABLE] to view a table of values of the function and its derivative.
