mod z= |  sin(π/6) / cos(π/4)|      calculate this by calculator u will get the answer


arg(z) =    tan-1 (sin(π/6) / cos(π/4))  


 


2)  draw the square (0,0) at origin define a A in the 1st quadrant because it has x as +ve and y also +ve


now go do define BCD from A point


u will find      B  by going anticlockwise from A.


or u will find      B   by going clockwise from A.


alpha has to be  first coordinate


beta has to be second coordinate


 


but this is square and how do we define square with A(2,1). it has to have 45 degree angles from origin to A because origin is its centre point.
