Given values b (where abs(b)<=1) and n (polynomial order), write a function that calculates atan(b) by using power series.
Please fix the test suite.
The arguments need to be supplied to the function, as in:
Test suite has been fixed. Thanks for the comments!!
There is still a problem with the test suite. The quantity ff is not defined in test suite problems 2 and 3.
The test suite has been fixed and improved.
Also, note that the input n (polynomial order) refers to the highest-powered term in the series, NOT the number of series terms.
