Dot product of two vectors is equal to cross product what will be angle between them?

(A1) The dot product of two vectors is a scalar and the cross product is a vector? ================================== (A2) The cross product of two vectors, A and B, would be [a*b*sin(alpha)]C, where a = |A|; b = |B|; c = |C|; and C is vector that is orthogonal to A and B and oriented according to the right-hand rule (see the related link). The dot product of the two vectors, A and B, would be [a*b*cos(alpha)]. For [a*b*sin(alpha)]C to equal to [a*b*cos(alpha)], we have to have a trivial solution -- alpha = 0 and either a or b be zero, so that both expressions are zeroes but equal. ================================== Of course one is the number zero( scalar), and one is the zero vector. It is a small difference but worth mentioning. That is is to say if a or b is the zero vector, then a dot b must equal zero as a scalar. And similarly the cross product of any vector and the zero vector is the zero vector. (A3) The magnitude of the dot product is equal to the magnitude of the cross product when the angle between the vectors is 45 degrees.

If the magnitude of the product A x B is equal to AB then?

Then, if A nd B are scalars, it is not really surprising. If A and B are vectors then they have the same direction.


The height of a triangle is 18 inches Find the length of the base if the area of the triangle is 63 square inches?

Since the formula for the area of a triangle is: A = .5 x h x b just go 63 = .5 x b x 18 then 63 = 9b 7 = b


What is the value of ab if a is 7 and b is 9?

3 x 7 x 7 x a x b


If a is equal to b. is not a equal to not b?

No because if a=4 and b=4 then a=b and not a can equal 6 and not b can equal 5 so ~a is not = to ~b


When does the product of 2 integers equal zero?

When one or both of the integers is/are zero.a*b=0 if a=0, b=0, or both a and b are equal to 0. In other words, if one or both integers are zero.


Which two negative consecutive odd integers have a product of 63?

-9, -7 You could use an equation to figure this out. x is the first number and x+2 is the second number. The equation becomes (x)(x+2) = 63. x comes out to b 7, and x plus 2 is 9. Since a negative times a negative is a positive, those numbers can be changed to -7 and -9.

What is the LCM for the numbers 63 and 15?

LCM(a,b) = (ab)/(GCF(a,b)) 63 factors to [3 3 7] 15 factors to [3 5] common factors: [3] 63 * 15 / 3 = 315 ■


What is the product of two whole numbers if their sum is 20 and positive difference is 6?

The product of the two whole number is 13*7=91 This is because when u add both equations (a+b=20 with a-b=6) then u can get a=13 and b=7


If a is equal to b then not a is equal to not?

A = B !A = !B So Not A = Not B


What is the mathematical term the product of the mean equals the product of the extremes?

: The product of the means is equal to the product of the extremes. When you cross multiply to show 2 fractions are equivalent. Ex a/c =b/d so cross multiplying would show a x d = c x b c x b are the means a x d are the extremes Their products are equal in a proportion or equivalent fractions that is the answer and it is correct


3 times the larger of two numbers is equal to 4 times the smaller The sum of the numbers is 21. find the numbers?

a + b = 21 so a = 21 - b; 3a = 4b so 3(21 - b) = 4b ie 63 - 3b = 4b so 7b = 63 making b = 9 and a = 12


What plus what equals 163?
