WebDefinition (Real and Imaginary Parts) If z = x + i y then x is the real part of z and y is the imaginary part of z. Write Re ( z) for the real part of z and write Im ( z) for the imaginary part of z. Both the real and imaginary parts of a complex number are real! We have defined a complex number to be an expression x + i y where x and y are real. WebOne of the most fundamental equations used in complex theory is Euler's formula, which relates the exponent of an imaginary number, e^ {i\theta}, eiθ, to the two parametric equations we saw above for the unit circle in the complex plane: x = cos ⁡ θ. x = \cos \theta x = cosθ. y = sin ⁡ θ. y = \sin \theta. y = sinθ. red i 45 joist red humana bogota
