7.1 Numerical Approximations
In the course of scientific investigation, finding exact answers may not be possible at times. Instead of devoting a lot of effort trying to find an exact answer by solving the problem analytically, another alternative is to develop methods to produce approximate answers. This is particularly true for solutions involving irrational numbers like pi. You can choose the number of significant digits to be used with pi and determine the accuracy of the result.
The degree of accuracy required always depends on the targeted ...
