Question..........

Answer 1

Modulus of \[2(\cos \frac{ \pi }{ 3},iSin \frac{ \pi }{ 3 })\]

Answer 2

I suppose De-Moivres law Would help....

Answer 3

Answer 4

express above in the form of complex number , that is,
z = 2cos(pi/3) + i 2sin(pi/3)
then take modulus of this u will get the required answer

Answer 5

Modulus of \[a+ib \ is \sqrt{a^2+b^2}\]
Use the same thing here, in fact modulus of
\[\cos \theta+i\sin \theta =1\]
regardless of theta.Can you do it now?

Answer 6

So the answer is 2 ?

Answer 7

Yes

Answer 8
