If `|z-3i|=3 and amp z in (0, pi/2),` then `cot(amp z)-theta/z` is eqaul to

If |z-i|=1 and amp(z)=(pi)/(2)(z!=0), then z is

if |z|=4 and amp.z=(5 pi)/(6) then z

Given |z| = 14 and amp z = (7pi)/(6) , then z is =

If 0ltamp(z)ltpi,' then 'amp(z)-amp(-z) is equal to

If 0ltamp(z)ltpi, then amp(z)-amp(-z) is equal to

If 0ltamp(z)ltpi,' then 'amp(z)-amp(-z) is equal to

if |z|=4 and amp.z=5 pi/6 then z equals

If 0ltamp(z)ltpi,"then"amp(z)-amp(-z) is equal to

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|=4 and amp(z)=(5 pi)/(6) then write z in the form x+iy,x,y varepsilon R.
