Express the following complex numbers in the form

Given complex number is






We know that i2=-1





We know that the polar form of a complex number Z=x + iy is given by Z=|Z|(cos θ+ i sin θ)


Where,


|Z|=modulus of complex number


θ = arg(z)=argument of complex number


Now for the given problem,











Since x<0,y<0 complex number lies in 3rd quadrant and the value of θ will be as follows -1800≤θ≤-900.



.




The Polar form of is .
