Doing cross product
Weba × (b + c) = a × b + a × c, (b + c) × a = b × a + c × a, where a, b, and c are vectors in R3 and y is a scalar. (These properties mean that the cross product is linear.) We can use these properties, along with the cross product of the standard unit vectors, to write the formula for the cross product in terms of components. WebAnd you multiply that times the dot product of the other two vectors, so a dot c. And from that, you subtract the second vector multiplied by the dot product of the other two vectors, of a dot b. And we're done. This is our triple product expansion. Now, once again, this isn't something that you really have to know.

WebThen the cross product requirement for a magnitude of 0: The sine of the angle between the vectors is 0, sin(p) cannot be true, because sin and cos are not equivalent functions. Therefore, if a dot and cross product are both equal to 0 for the same vectors a and b, then either a or b (or both) must be a null vector.
