If z is a complex number, then amp `((z-1)/(z+1))=pi/2` will be

If z=((1+isqrt3)^2)/(4i(1-isqrt3)) is a complex number then a. arg(z)=pi/4 b. arg(z)=pi/2 c. |z|=1/2 d. |z|=2

If z=((1+isqrt3)^2)/(4i(1-isqrt3)) is a complex number then a. arg(z)=pi/4 b. arg(z)=pi/2 c. |z|=1/2 d. |z|=2

If z be the complex number such that |z+(1)/(z)|=2 then minimum value of (|z|)/(tan((pi)/(8))) is

If z is a complex number such that zbarz = 1 and amp frac{z}{bar z}= frac{pi}{2} then z= ________.

Let z be a complex number , if |z| = 3 and amp z = ((-pi)/(4)) then the modulus- amplitiude form of z is z =

If z_(1) and z_(2) are complex number and (z_(1))/(z_(2)) is purely imaginary then |((z1+z2)/(z1-z2))|=

If 0 lt amp(z) lt pi , then amp(z) - amp(-z) =
