Functions can be injections (one-to-one functions), surjections (onto functions) or bijections (both one-to-one and onto). Informally, an injection has each output mapped to by at most one input, a surjection includes the entire possible range in the output, and a bijection has both conditions be true. This concept allows for comparisons ...To draw a vertical line on a coordinate plane.

Choose any point on the line and label it 0. This point is called the origin. Choose a convenient length. Starting at 0, mark this length off in both direc­tions, being careful to make the lengths about the same size. In a wide sense, as argued below, the answer is no. Indeed, R(z) ℜ ( z) is not a holomorphic function since its image is the real line. In this sense, there is no formula for R(z) ℜ ( z) that does not involve z¯ z ¯, because the Cauchy–Riemann equations fail for R(z) ℜ ( z) : This was said already in the comments.Answer: A complex number is defined as the addition of a real number and an imaginary number.
