What does “Cross product” actually mean in Vectors & 3D Geometry, and why does it matter for JEE?
a×b = |a||b|sinθ·n̂ gives a vector perpendicular to both a and b.
In simple words: a×b = |a||b|sinθ·n̂ gives a vector perpendicular to both a and b. Getting Cross product clear matters because JEE questions on Vectors & 3D Geometry usually test this idea directly, not just a formula you memorised.
Key point
Cross product
Common mistake
expecting the cross product to be a scalar.
Memory tip
cross product → vector; its length is the parallelogram's area.
