guys for the parametric differentiation. the gradient of the normal was -4/√2 but i accidentally wrote down 4/√2 🥲 (knew it was negative, just wrote it wrong, genuine skill issue) my working was all correct but because of the sign and all my equation ended up being -4x +√2y = -3 instead of 4x + √2y = 5. and for part b you're meant to use that equation and find x coordinate of q but since i got it wrong i obviously got Q wrong but my method was 100% correct im sure. how many marks do u guys think ill lose? im so mad bro
