the stuff we learn in PPV(Polar coordinates, Paramatric equations and vectors) is quite useful i say, but its still getting to me, especially wif the extremely long equations like: dy/dx = (dr/d(-) sin(-) + r cos(-) )/(dr/d(-) cos(-) - sin (-)) where (-) is thetha
so..., i dun think i'll even bother wif math honours next yr. but it does seems useful though..... i used paramatric equations to totally hack a qns in NCT, and vectors to make electric motors a piece of cake..... so...... zzz IDK
