I dont think we require many formulae for 3D
most of the results are short and "derivable" in quick time...

except ofcourse those of scalar and vector products of 3 or more vectors.

unlike 2D where we must know the different forms and eqns to save time and space

@philip Yes derivation is imp. but remembering the results will surely save time.,..thats how i feel.

@tiitians....more suggestions needed
