What is the cross and dot product? And what is "n cap" in cross product... a x b = absin@ "n cap" . Plz explain with example...
Hi Hasan,
Dot prodouct of two vectors is the operation on vectors which will yield you a scalar.
And cross roduct is an operation on vectors which will yield you another vector.
So axb = |a|*|b|*sinx*"n-cap", where "n-cap" is a unit vector perpendicular to the plane containing "a" and "b".
And a.b = |a|*|b|*cosx ----------(which is a scalar, as RHS has no vectors).
Hope that helps.
Best Regards,
Ashwin (IIT Madras).
thanks lot....
