What is the cross product of -i x i? Is it negative 1 or is still just 0?
This equation for the projection isRy122 said:i used the equation
w=v.((u.v)/(modulusv^2))
A vector cross product is a mathematical operation that calculates a new vector that is perpendicular to the two original vectors. It is denoted by the symbol "x" and is commonly used in physics and engineering.
To calculate a vector cross product, you need to use the following formula:
A x B = (AyBz - AzBy)i + (AzBx - AxBz)j + (AxBy - AyBx)k
Where A and B are the two vectors and i, j, and k represent the unit vectors in the x, y, and z directions respectively.
The result of the cross product of two parallel vectors is always a zero vector (0, 0, 0). This is because the angle between two parallel vectors is 0 degrees, and the sine of 0 is also 0, making all components of the cross product equal to 0.
Yes, the order of the vectors is important when calculating a cross product. Switching the order of the vectors will result in a vector with the opposite direction.
If the cross product of two vectors is equal to zero, it means that the two vectors are either parallel or antiparallel to each other. This means that they either have the same direction or opposite directions, respectively.
