1Same doubt here...vectors chapter in both cartesian and vector form ????
1I 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
24@philip Yes derivation is imp. but remembering the results will surely save time.,..thats how i feel.
@tiitians....more suggestions needed
