What is the trigonometric form of a complex number?
The standard form of a complex number is the cartesian one; a plane with orthogonal axes for real parts and imaginary parts. A complex number has a pair of co-ordinates defining its position on the plane. A trigonometric form is a plane with an origin, and one line from the origin to infinity. A complex number is defined by its distance from the origin and the angle between the datum line and the line joining the number to the origin. It is just like co-ordinate geometry with co-ords r, theta instead of x,y.

What are set of complex number?
Complex numbers are numbers of the form (x + yi) where x and y are real numbers and i is the imaginary square root of -1. Any collection of such numbers is a set of complex numbers.
What is the standard form of complex numbers?
a + bi. a & b are both real numbers. the number i is the imaginary unit equal to the positive square root of -1.
