I am finding problem in evaluating the flowing function using Rouché's theorem. I have looked out for examples but it lacks the explanation and steps to reach the required output.
I need to determine the number of zeros of the function f(y) = y^5+14y+1 for 1 < |y| < 2
I have understood that i need to break it into 2 parts.
If you could help me out.
Thank you !
