Question

2. Represent the following complex numbers in the standard form x + iy
i)cos 2pi/3 + i sin2pi/3​

Answer 1

Answer:

Represent the following complex numbers in the standard form x + iy

i)cos 2pi/3 + i sin2pi/3​

Step-by-step explanation:

cos 2pi/3 + i sin2pi/3​

by putting the value of cos 2pi/3=-1/2  and sin2pi/3​= sqrt3/2

cos 2pi/3 + i sin2pi/3​

=$\frac{-1}{2}+i\frac{\sqrt{3} }{2} \\ \frac{-1+i \sqrt{3} }{2}$
