How to find polar form and cartesian form of th......

Hi,

Was wondering if I could get some insight on how to tackle this problem.

[The problem is: "By Writing the complex numbers in polar form, , find a value for the quantity . Give your answer in Cartesian form,

How would I find the R in this problem? In the back of the book, it says r is equal to square root of two

To find r, I did the following thus far

then took square root of 2.73205 (used formula for a right hand triangle where x is


help would be apreciated

pleaseeeee
