What does the x stand for in maths?
At the lower levels it stands for multiplication, at more advanced levels it stands for the cross product of vector multiplication (in three or seven dimensions). The multiplication operator can also be a dot on the line ( . ), a dot above the line ( 𝆴 ), an asterisk ( * ), and probably some other symbols as well.
What is the column vector?
In mathematics a vector is just a one-dimensional series of numbers. If the vector is written horizontally then it is a row vector; if it's written vertically then it's a column vector.Whether a vector is a row or a column becomes significant usually only if it is to figure in multiplication involving a matrix. A matrix of m rows with n columns, M, can multiply a column vector, c, of m rows, on the left but not on the right.That is, one can perform Mv but not vM. The opposite would be true for a row vector, v, with 1 row and m columns.
What is null vector?
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
What is a unit vector?
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
What are all the symbols for multiplication?
There 3 to 4 symbols of multiplication depending on the condition.If you are using computer for calculation the only symbol of multiplication is *.If you are using calculator the symbol for multiplication is x.If you are solving equation in paper the symbol for multiplication b/w variables are mostly represent by a dot(.) or the place is left empty. A.B or AxB the answer will be same is scalar calculation but will be different on vector calculation. If use scalar calculation 'AB' will also represent multiplication b/w two variables. But it is only applicable on variables.If we use scalar number in equation like 3(4-3)*3=9; here '3(' is representing the multiplication b/w the number and the bracket. If there is any number before a bracket without any symbol then this will show that the number is multiplying by the bracket values.
