The Solver mode is used to solve one unknown variable by inputting known variables.

There are three methods: Equation, Newton’s, and Graphic. The Equation method is used

when an exact solution can be found by simple substitution. Newton’s method implements

an iterative approach to find the solution once a starting point is given. When a starting

point is unavailable or multiple solutions are expected, use the Graphic method. This

method plots the left and right sides of the equation and then locates the intersection(s).

Solving a Literal Equation Using the Graphic Method

(Volume of a Cylinder)

1. Find the radius of a cylinder with a volume of 30in

and a height of 10in, using

the Graphic method.

2. Save the formula as “V CYL”.

3. Find the radius of a cylinder with a volume of 200in

and a height of 15in,

using the saved formula.

Use the Graphic method to find the radius of a cylinder giving the range of the unknown

variable.

The formula : V =

h ( V = volume r = radius h = height)

Example
