can anyone explain me as how it comes to 0.06 degrees

<(1+j) - <(1 + (j+.2%))

the answer for this expression is 0.06 degrees

and the lower_than symbol denotes the angular symbol here.'


thanks in advance
 

Hi
this expression can be written as
arctan(1)-arctan(1.002)
derivative of arctan()=1/(1+x^2) so its 1/2 at point x=1. thus
arctan(1)-arctan(1.002)=-1/2*0.002=-0.001 rad = -180/pi*0.001 deg = -0.06 degree

Regards, pavel.
