Two adjacent sides OA and OB of a rectangle `OACB` are represented by `vec a and vecb` respectively, where o is origin. If `16|vec axxvecb| = 3 |veca+vecb|^2` and `theta` is the angle between the diagonals OC and AB, then the value(s) of `tan(theta/2)`

Two adjacent sides OA and OB of a rectangle OACB are represented by vec a and vecb respectively, where o is origin. If 16|vec axxvecb| = 3 (|veca|+|vecb|)^2 and theta is the angle between the diagonals OC and AB, then the value(s) of tan(theta/2)

The adjacent side vectors vec(OA) and vec(OB) of a rectangle OACB are veca and vecb respectively, where O is the origin . If 16|veca xx vecb|=3(|veca|+|vecb|)^(2) and theta be the acute angle between the diagonals OC and AB then the value of cos(theta/2) is : (a) (1)/(sqrt(2)) (b) (1)/(2) (c) (1)/(sqrt(3)) (d) (1)/(3)

If veca and vecb are unit vectors and theta is the angle between them then show that |veca-vecb|=2sin.(theta)/(2)

vecA and vecB are two vectors and theta is the angle between them, if |vecA xx vecB|=sqrt(3)(vecA.vecB) the value of theta is:-

If vec(e_(1)) and vec(e_(2)) are two unit vectors and theta is the angle between them, then sin (theta/2) is:

If veca,vecb are two unit vectors such that |veca + vecb| = 2sqrt3 and |veca -vecb|=6 then the angle between veca and vecb , is

The angle between the vectors vecA and vecB is theta. The value of vecA(vecAxx vec B) is -

If veca and vecb asre two vectors such that |veca|=2, |vecb| = 7 and vecaxxvecb=3hati+6hatk find the angle between veca and vecb

If veca=2hati-hatj+hatk,vecb=3hati+4hatj-hatk and let theta be angle between. Find the value of sintheta .

If veca , vecb and vec(c ) are there vectors such that veca + vecb = vec(C ) and further a^2 +b^2 =c ^2 find the angle between veca and vecb ?
