>teacher comes in to teach us about this exciting new topic called 'polar coordinates'

he teaches us them and i understand the basics but what i dont understand is why? why is this better than the typical/ordinary coordinate system we're all used to? i'm sure there's a reason so would someone be kind enough to explain it so i'll understand, thanks
