Complex Number
Complex Number
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1.
Expansion of sin^n θ and cos^n θ
Expansion of sin^n θ and cos^n θ
The expansion of sin^n θ and cos^n θ in terms of sines and cosines of multiples of θ. This expansion is helpful to simplify trigonometric expressions and solve problems involving complex numbers.
Powers and Roots of a Complex Number
Powers and Roots of a Complex Number
The process of finding the powers and roots of a complex number. This can be achieved using De Moivre's theorem, which states that for any complex number z = r(cosθ + i sinθ) and any integer n, z^n = r^n(cos(nθ) + i sin(nθ)).
