lol.
ouch. that's terrible.gurmies said:First Extension Maths assessment this year, question 1, (2x-1)^3...began expanding using pascal's triangle (not a fan of formula) went 1 3 3 1
then cubed all the x's and not the 2...ended up with 2x^3-6x^2+6x-1....
same exam question was 3sec^2x = 3 + tanx, stupid me replaced sec^2x with 1-tan^2x rather than 1 + tan^2x...came first nonetheless =)
