If a complex number having absolute value of √2 is making 45° angle with x-axis in third quadrant, then it can be written as –
1
[r, θ] = \(\left[ {\sqrt 2 ,\frac{{3\pi }}{4}} \right]\)
2
[r, θ] = \(\left[ {\sqrt 2 ,\frac{{\pi }}{4}} \right]\)
3
[r, θ] = \(\left[ {\sqrt 2 ,-\frac{{3\pi }}{4}} \right]\)
4
[r, θ] = \(\left[ {\sqrt 2 ,-\frac{{\pi }}{4}} \right]\)
