vectorA*vector B=ABsin@n^
=ABsin@(cos@/cos@)n^
=ABcos@(sin@/cos@)n^
=vector A.vector B(tan@)n^
where@ is the angle between the vectors.
=ABsin@(cos@/cos@)n^
=ABcos@(sin@/cos@)n^
=vector A.vector B(tan@)n^
where@ is the angle between the vectors.

Answer:
Explanation:
Magnitude of a × b in terms of scalar products.
a×b=absinθ
a.b=abcosθ
=a×b=a.btanθ
We get, a×b=a.btanθ
