How to multiply and divide two complex numbers in trigonometric form?
Multiplying and dividing two complex numbers in trigonometric form: To multiply two complex numbers, you multiply the moduli and add the arguments. To divide two complex numbers, you divide the moduli and subtract the arguments. z 1= 3(cos 120º + isin 120º) z
How to find the modulus of Z in trigonometric form?
The trigonometric form of a complex number z= a+ biis z= r(cos\u0012+ isin\u0012); where r= ja+ bijis the modulus of z, and tan\u0012=b a is called the argument of z. Normally, we will require 0 \u0014\u0012<2ˇ.
What is the argument of Z in trigonometric form?
The trigonometric form of a complex number z= a+ biis z= r(cos+ isin); where r= ja+ bijis the modulus of z, and tan=b a is called the argument of z. Normally, we will require 0 <2ˇ.
How do you find the standard form of a complex number?
Complex numbers can be written as z= a+bi, where aand bare real numbers, and i= p 1. This form, a+ bi, is called the standard form of a complex number. When graphing these, we can represent them on a coordinate plane called the complex plane.

So a complex number of length 1 has the form . Hence: Any complex number can be written in the form , where r is a positive real number and is the unit vector that makes a counterclockwise angle of degrees with the positive real axis. We have illustrated this for z in the first quadrant; similar pictures can be drawn for z in any other quadrant.
