change it into cartesian form `(cos((3 pi)/(4))-i sin((3 pi)/(4)))`

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

cos((3pi)/4+x)-sin(pi/4-x)=?

write in the form A+iB[1+cos((pi)/(3))+i sin((pi)/(3))]^(6)

sin^(-1)(cos((3 pi)/(4)))

.Convert polar co-ordinate into cartesian co-ordinates. (2,(3 pi)/(4)), (ii) (1,(pi)/(2)

The continued product of the four values of (cos((pi)/(3))+i sin((pi)/(3)))^((3)/(4)) is

The continued product of the four values of (cos((pi)/(3))+i sin((pi)/(3)))^((3)/(4)) is

cos A+cos((4 pi)/(3)-A)+cos((4 pi)/(3)+A)=0

Find the modulus and argument of the following complex number and correct then in polar form: (i-1)/((cos pi)/((cos pi)/(3)+i(sin pi)/(3)))

If the polar form of a complex number is sqrt(2)(cos(-(3 pi)/(4))+i sin(-(3 pi)/(4)) the real and imaginary parts in the cartesian form respectively,are a).-1 and -1 b)-1 and 0 c).0 and -1 d)-1 and 1
