Complex Numbers And Quadratic Equations — Syllabus & Topics

Topics covered in Complex Numbers And Quadratic Equations for BITSAT Mathematics.

Topics in Complex Numbers And Quadratic Equations

1

Introduction to Complex Numbers

  • Complex number z = a + ib where a, b ∈ R and i = √(-1)
  • Real part Re(z) = a, Imaginary part Im(z) = b
  • Two complex numbers are equal if their real and imaginary parts are equal
2

Algebra of Complex Numbers

  • Addition: (a + ib) + (c + id) = (a + c) + i(b + d)
  • Multiplication: (a + ib)(c + id) = (ac - bd) + i(ad + bc)
  • Division involves multiplying by conjugate of denominator
3

Modulus and Conjugate

  • Conjugate of z = a + ib is z̄ = a - ib
  • Modulus |z| = √(a² + b²) represents distance from origin
  • z × z̄ = |z|² = a² + b²
4

Argand Plane and Polar Form

  • Complex plane with real axis (x-axis) and imaginary axis (y-axis)
  • Point (a, b) represents complex number a + ib
  • Polar form: z = r(cos θ + i sin θ) = re^(iθ)

Key Concepts

A complex number z =AdditionThe imaginary unit i followsFor z = a + ibComplex numbers are represented as points
