i still neeed help

apoorvk · Answer

Okay no probs..

Do you have any idea what polar coordinates are?

apoorvk · Answer

$$2(\frac12 + \frac{\sqrt 3i} 2) = r(cos\theta + \iota sin\theta )$$


Compare and find 'r' and 'theta'.

Polar form = (r, theta)

Okay if,
$$z= x +  iy$$

then, 

$$|z| = \sqrt{x^2 + y^2}$$

|z| --> modulus.


Can you use this?
