A complex number is in the form of a + ib; a = real part and b = imaginary part
Let z1=a+ib and z2=c+id, then:
z1+z2=(a+c) + i(b+d)
z2+z2=(ac-bd) + i(ad+bc)
For anynon-zero complex number z=a+ib (a≠0,b≠0), there exists the complex numberdenoted by 1/z or z^(-1), called the multiplicative inverse of z such that = 1 + i0 = 1
For any Integer k,
the conjugate of the complex number is
the polar form of complex number z = x + iy is
A polynomial equation of n degree has n roots.
The
solutions of the quadratic equationax^2 + bx + c = 0, where a,b,c ϵ R, a≠0, b^2 - 4ac < 0, are given by
