A complex number is generally expressed in the form a + bi, where 'a' and 'b' are real numbers, and 'i' is the imaginary unit (√-1). The 'a' part is the real part and 'b' is the imaginary part
Complex Number Form: z = a + bi, where 'z' represents the complex number, 'a' is the real part (Re(z)), and 'b' is the imaginary part (Im(z))
Euler's Formula: eiθ = cos(θ) + i sin(θ)
