The second line is the solution. In many cases, as with this problem, Calchemy is able to derive the mathematical equation relating the variables for you, by dimensional analysis. That is, Calchemy uses the Units of the quantities, and their Physical relationship to obtain the solution. But that's harder, and you have to parenthesize more. If you would like to see the equation that Calchemy actually solved, you can mark Show Interpretations on the Calchemy Live equation entry form.
Confusion crops up when the units of two parameters, separated by semicolons, cancel.
In this case there will be multiple solutions , and you have to know your problem. Copyright 1996-2001 Calchemy Software Inc.
