Revision Notes — Complex Numbers And Quadratic Equations
Key concepts, formulas, and definitions from Complex Numbers And Quadratic Equations for BITSAT Mathematics preparation.
Key Topics to Revise
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
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
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
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)
