If `z` is a complex number such that `|z|=1,` prove that `(z-1)/(z+1)` is purely imaginary, what will by your conclusion if `z=1?`

If z is a complex number such that |z|=1, prove that (z-1)/(z+1) is purely imaginary, what will be your conclusion if z=1?

If (z-1)/(z+1) is purely imaginary then

(i)If z is a complex no.such that |z|=1; prove that (z-1)/(z+1) is purely imaginary.what will be the conclusion if z=1 (ii) Find real theta such that (3+2i sin theta)/(1-2i sin theta) is purely real

If |z|=1, prove that (z-1)/(z+1) (z ne -1) is purely imaginary number. What will you conclude if z=1?

If (z-1)/(z+1) is purely imaginary, then |z|=

If the number (z-1)/(z+1) is purely imaginary, then

If (z - 1)/(z + 1) is purely imaginary, then |z| is

If z(!=-1) is a complex number such that (z-1)/(z+1) is purely imaginary,then |z| is equal to

If z is a complex number such that (z-1)/(z+1) is purely imaginary, then the value of |z| is-
