If A B And C Are The Vertices Of A Dabc Then What Is The Value Of Vector Ab Ca
Ex 91, 3 Add the following (i) ab − bc, bc − ca, ca − ab Expressions are ab − bc bc − ca ca − ab We put like terms below like terms So, required sum = 0 Article byAnswer (1 of 5) As per the identity, (x\y\z)^2 = x^2\y^2\z^2\2xy\2yz\2zx Here, x = AB, y = BC and z = CA Putting this value, (AB\BC\CA)^2 = AB^2
