Thank you @Alfonso for the link it really helped me understand a bit more on the topic of stacked filters.
Could some one help point me in the direction to understand the last 2 test cases?
I currently have a solution that is correct for all the test cases except the last 2. Is there something special for these cases that would be causing me to be not quite converge. I am currently not meeting the tolerance, the difference of my result and the assertion test are:
9. 0.0019000
10. 0.056585
Thanks in advance.
