" (a) "quad (cos pi+i sin pi)

Find the value of (cos pi+i sin pi)

z = (1+cos6 pi)+i sin6 pi

The numerical value of (where i = sqrt-1 ) (cos pi/10 + i sin pi/10)(cos 2pi/10 + i sin 2pi/10) xx (cos 3pi/10 + i sin 3pi/10) (cos 4pi/10 + i sin 4pi/10) = ..........

The polar form of (i^(255))^(3) is (cos pi)/(2)+i(sin pi)/(2)bcos pi+is in pi c*cos pi-i sin pi d(cos pi)/(2)-is in(pi)/(2)

Write the complex number z = (i-1)/(cos pi/3 + i sin pi/3) in polar form.

Solve the following: Express the following number in the fome x + iy. sqrt(3) (cos (pi / 6) + i sin (pi / 6)

Solve the following: Express the following number in the fome x + iy. sqrt(2) (cos (pi / 4) + i sin (pi / 4))

One of the values of ((cos (pi)/(6)-i sin (pi)/(6))^(1 / 2))((cos (pi)/(6)+i sin (pi)/(6))^(1 / 2)) is
