approximation

[mcgrim]

Thanks,
I understand what you are saying,
I came up with a correction to my code, however
my graphs are still empty.
I'd like to know why so and what I should do in order
to solve this issue.

def applog(n,x):
    a0=(1+x)/2
    b0=sqrt(x)
    for i in range(n):
        a0=(a0+b0)/2
        b0=sqrt((a0)*b0)
    return (x-1)/a0
 



print("the log approximation is: " , ((applog(100,4)))) 
print("log value-------------------:" , (np.log(4)) )
                  
error=(abs( applog(100,4)- (np.log(4))   ) )                    
print("the error is : ", error)   
    
 
plt.show()
plt.plot((applog(100,4)) )
plt.plot(np.log(4))
plt.show()          #should plot both funtctions in the same graph
plt.plot(error )
plt.show()         # should plot the difference of both functions
