Different answers for the two ways of computing formulas for parallel resistors
Demonstrate that Lem is right. Investigate the behavior of the system on a variety of arithmetic expressions. Make some intervals
A
and
B
, and use them in computing the expressions
A/A
and
A/B
. You will get the most insight by using intervals whose width is a small percentage of the center value. Examine the results of the computation in center-percent form (see exercise
2.12
).
