**BINNOY**- Replies: 6

I recently discovered the true purpose of complex numbers.

They were in a way used to describe rotation or inclination.

i = inclination by 90 degree

i * i = inclination by 180 degrees = -1

i * i * i = inclination by 270 degree = -i

i * i * i * i = inclination by 360 degree = 1

So now lets consider a number like 3 + 4i.

3 is the horizontal component of the number(real part)

4 is the vertical component of the number.(imaginary part)

Hope this would be helpful to someone who stumbles upon.
