Introduction to Complex Numbers (MEX-N1)
Module overview →- How are complex numbers represented, added, multiplied and divided, and how does the Argand plane give them geometric meaning?Represent complex numbers in Cartesian and polar form, perform arithmetic, and interpret modulus, argument and conjugate geometrically on the Argand plane6 min answer →
