    27/10/2009 · hey guys does anyone know how to find the normal of a point on a sine wave? i know that the slope (tangent) of a sine wave is the cosine wave, so i can use that to calculate the tangent at a point on a sine wave. However that is y/x and i dont know how to get the individual x and y comp... Why use sine and cosine when resolving vectors into components? Ask Question Asked 2 years, 5 months ago. why does the horizontal component have to be $5\cos 35^{\circ}$, why can't it be $5 \cdot We use the sine and cosine to decompose a vector into its horizontal and vertical components because the definition of sine and cosine

    scalar-vector multiplication. the dot product of any vector with itself is the square of that vector's magnitude. A · A = AA cos 0° = A 2. Applying this corollary to the unit vectors means that the dot product of any unit vector with itself is one. Group terms by unit vector and factor. the sine series expansion of associated Legendre polynomials has been derived based on well-known recurrence formulae. The resulted formulae are subsequently empirically tested for errors to determine the limitations of its use, and strong dependence on the co-latitude has been found.

    vector in terms of i and j cos and sine

    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.
