Binary operation properties
Associativity, commutativity, identity, inverse.
Relation types
Reflexive, symmetric, transitive; image as function's range.
Complex number parts
Real part, imaginary part, modulus, argument.
Complex Number — parts?
Real and imaginary parts.
Modulus — definition?
Distance from origin, $|z| = oot2 rom a^2 + b^2$.
Argument — role?
Angle with positive real axis.
Polar form — purpose?
Simplifies multiplication, division.
De Moivre's theorem — use?
Raising to powers, extracting roots.
Binary operation — property?
Combines two elements within a set.
Associativity — meaning?
Order of grouping doesn't matter.
