Task 1

Add a documentation to the function newtonInv from session 4, such that ?newtonInv displays the following information:

newtonInv(x::Real,y0=0.1;iterations=10)

Calculate an approximation of the inverse of x by using the iteration $y_{k+1} = 2*y_k - y_k^2*x$ with inital value $y_0$ = y0.

Examples

Main Example

julia> newonInv(2)
0.5



In [2]:

    
"""
