`z=cos(pi/6)+isin(pi/6)=?`

cos(pi/4)+isin(-pi/4)=?

(cos(pi/6)+isin(pi/6))^7=?

-2(cos(pi/3)+isin(pi/3))=?

z=5(cos((7pi)/6)+isin((7pi)/6))=?

sin(pi/3-x)cos(pi/6+x)+cos(pi/3-x)sin(pi/6+x)=1

If z = cos"" pi/4+ isin (pi/6) ,then

If z=cos((pi)/(4))+i sin((pi)/(6)), then

Find the absolute values and arguments of the following complex numbers: (i) 3(cos60^(@)+isin60^(@)) (ii) "icos"(pi)/(6)+"sin"(pi)/(6) (iii) 1-costheta+isintheta .

7(cos((-5pi)/6)+isin((-5pi)/6))=?
