One way to generate sine and cosine is to track the motion Sine and cosine from rotating vector Khan Sure, you can write your vector in polar form, and since$\hat r$is by definition a unit vector, it will have the form you mentioned: $$\hat r = \cos\theta\hat i + \sin\theta\hat j$$ for some angle$\theta$. Whether this is better or worse than the rectangular form$\hat r = a\hat i + b\hat j… 16/10/2006 · I don't understand how your last statement can be true. If the statement of the problem means that ship B is heading 60 degrees North of East, then you have the sine and the cosine reversed. The northward component is the sine term and the eastward component is the cosine term. But then you should have gotten the first part wrong.
