If mode z =1 and w=z-1/z+1 where zis not equal to -1 then real part of z

Hii Sargun..

You can't find real part of z until mod w is given. Check out the below answer with corrected question.

Given that mod z=1

and w=z-1/z+1

conjugate of z+1 is z bar +1

So multiply and divide with z bar+1

w=(z-1)(zbar+1)/(z+1)(zbar+1)(equation 1)

we know that z*zbar = (mod z)^2=1(equation 2)

and z+zbar= 2x(equation 3)

and z-zbar= 2iy(equation 4)

After simplyfying equation 1 substitute equation 2,3, 4 in it

You will get w=yi/(1+x)

So "w" don't have real part, hence real part of "w" is 0.

Hope this helps you. All the best.

Mode Formula . The mode is the number that appears most often in a set of numbers. The mode is the most frequently occurring value. Like the statistical mean and median, the mode is a way of capturing important information about a random variable. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. If mode is 1 and w=z+1 than, z=w-1
