Θ Solve for y.

The result is 0.149836.., i.e., y = 0.149836.

Θ It is known, however, that there are actually two solutions available for

y in the specific energy equation. The solution we just found

corresponds to a numerical solution with an initial value of 0 (the

default value for y, i.e., whenever the solution field is empty, the initial

value is zero). To find the other solution, we need to enter a larger

value of y, say 15, highlight the y input field and solve for y once

The result is now 9.99990, i.e., y = 9.99990 ft.

This example illustrates the use of auxiliary variables to write complicated

equations. When NUM.SLV is activated, the substitutions implied by the

auxiliary variables are implemented, and the input screen for the equation

provides input field for the primitive or fundamental variables resulting from the

substitutions. The example also illustrates an equation that has more than one

solution, and how choosing the initial guess for the solution may produce those

different solutions.
