If vec p and vec q are unit vectors forming an angle of 30^(0); find the area of the parallelogram having vec a=vec p+2vec q and vec b=2vec p+vec q is its diagonals.

(22) if vec p and vec q are unit vectors forming an angle of 30^@ ; find the area of the parallelogram having veca=vecp+2vecq and vecb=2vecp+vecq as its diagonals. (23) For any two vectors vec a and vec b , prove that | vec a xxvec b|^2=| [vec a* vec a ,vec a*vec b],[ vec b* vec a, vec b* vec b]| .

If vec a=2 hat i-3 hat j+ hat k ,\ vec b=- hat i+ hat k ,\ vec c=2 hat j- hat k are three vectors find the area of the parallelogram having diagonals ( vec a+ vec b)\ a n d\ ( vec b+ vec c)dot

What will be the angle between vec A and vec B , if the area of the parallelogram drawn with vec A and vec B as its adjacent sides is 1/2 AB ?

If a=2hat i-3hat j+hat k,hat b=-hat i+hat k,vec c=2hat j-hat k are three vectors,find the area of the parallelogram having diagonals (vec a+vec b) and (vec b+vec c)

If a=2hat i-3hat j+hat k,hat b=-hat i+hat k,vec c=2hat j-hat k are three vectors,find the area of the parallelogram having diagonals (vec a+vec b) and (vec b+vec c)

If vec a = 2vec i-3vec j + vec k and vec b = -vec i + vec kvec c = 2vec j-vec k then the area of the parallelogram is having diagonals vec a + vec b and vec b + vec c is
