What is value of a cross A?

What is value of a cross A?

A×A=0.

Why a cross B is not equal to b cross a?

vector product of two vectors is not commutative that is A cross B not equal to B cross A . In this case magnitudes are equal but directions are opposite. It can be A cross B = -B cross A.

Is a cross B is equals to B Cross A?

If A and B are two vectors, then A cross B is not equal to B cross A.

What is the difference between a cross B and B cross a?

Answer. vector product of two vectors is not commutative that is A cross B not equal to B cross A . In this case magnitudes are equal but directions are opposite. It can be A cross B = -B cross A.

What is the angle between a cross B and B cross a?

Answer: Anyway from this, we know that the A×B vector and B×A vector are equal in magnitude but in opposite direction, i.e they are antiparallel, so the angle between them is 180° or π rads.

What is the angle between vector A * B and B * A?

The angle between them is 180 ° . as both are opposite of each other.

What is angle between AXB and BXA?

Kajal answered this. The angle is 180 degrees since the direction of A×B is vertically opposite to the that if B×A. Remember A×B=-B×A.

What is the angle between the vector AxB and Vectorbxa?

Answer. Explanation: If AxB = BxA, then BxA = -(BxA), so AxB = 0. This only happens if the angle between A and B is 180 or 0 degrees or if A or B is the 0 vector, but then talking about angles between the vectors is meaningless.

For which sets a B do we have AxB BxA?

Then in AxB we can first replace first ‘A’ with ‘B’ (As by assumption A=B) so that it becomes BxB. Now we have AxB=BxB. In the next step we replace ‘B’ with ‘A’ so that BxB can be written as BxA.

Is AA subset of AxB?

More formally, Given sets A, B (A-domain, B-codomain) AxB= {(a,b)I a∈A, b∈B} A function is a subset of AxB such that each element a has a unique b in the pair (a,b).
