ABSTRACT
There are three ways of expressing a complex number:
z = ( a + jb) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429294402/968186b9-ffa4-4f2b-aa54-7fc58a604561/content/eq2448.tif"/> , called Cartesian or rectangular form,
z = r ( cos θ + j sin θ) https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429294402/968186b9-ffa4-4f2b-aa54-7fc58a604561/content/eq2449.tif"/> or r∠θ, called polar form, and
z = r e jθ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429294402/968186b9-ffa4-4f2b-aa54-7fc58a604561/content/eq2450.tif"/> called exponential form.
