Question

Write down the geometrical meaning of modulus of a complex numbe​

Answer 1

The modulus (or magnitude) is the length (absolute value) in the complex plane, qualifying the complex number z=a+ib z = a + i b (with a the real part and b the imaginary part), it is denoted |z| and is equal to |z|=√a2+b2 | z | = a 2 + b 2 .
