Let be three vectors. Then, scalar triple product is equal to :
D.
Since if are cyclically permuted the value ofscalar triple product remain same.
The solution of the differential equation sec2(x)tan(y))dx + sec2(y)tan(x))dy = 0 is :
None of these
are three vectors with magnitude and such that is perpendicular to , is perpendicular to is perpendicular to . It follows that is equal to :
