10 and press ENTER. A now has the value 10, and the highlight moves to B. You can also type simple math problems in an input
form. For example, type 5
SOLVE menu key. Shortly, the result 26.9258... is returned.
33. What if C remains the same, but A changes to 15? What should B change to? You don't have to rewrite your equation to find out.
Press the DOWN cursor key twice to select A. Type 15 ENTER and now with B selected, press the SOLVE menu key. The result,
22.36... appears. In this way, any variable in any part of the equation can be solved without re-entering all the data.
34. Numerical solvers can often return several results, especially for functions that are periodic, (SIN, COS), as well as many
polynomials. Let's examine how this works.
