Answer 1

Rectangular form usually allow to perform addition and subtraction where polar form allow to perform  multiplication and division. To convert rectangular form to polar form it involves some trigonometric forms , follow the steps below:

1. Find R by the formula:  

$R =\sqrt{x^2+y^2}=\sqrt{ 1+1} =\sqrt 2$  

2. Find tan t using the formula:

            tan t =$\frac yx$  

            tan t =$\frac11$

3. Using the arctan function of the calculator

t = $\frac{\pi}{4}$ or 45°
