A complex number is the sum of a real number and an imaginary number, written in the form a+bi. polar coordinate system The polar coordinate system is a special coordinate system in which the location of each point is determined by its distance from the pole and its angle with respect to the polar axis. And since the rectangular form of a Complex Number is a + bi, just replace the letters: a + bi = r*cos (θ) + r*sin (θ)i ← The right-hand side is a Complex Number in Polar Form. Take a look at the difference between a Polar Form and a Polar Coordinate. (16 votes) between a complex number in rectangular form and polar form can be made by letting θ be the angle (in standard position) whose terminal side passes through the point (a, b). ⇒ sin b r θ= cos a r θ= tan b a θ= rb.

Usually, we represent the complex numbers, in the form of z = x+iy where ‘i’ the imaginary number. But in polar form, the complex numbers are represented as the combination of modulus and argument. What is the Polar Form of any Complex Number? The polar form of a complex number is one way to represent a complex number apart from the rectangular form. Usually, complex numbers can be represented, in the form of z equals x + iy where ‘i’ equals the imaginary number.
