# parrametric equations C4 watch

1. find gradient when t=2 given x=3t^2 Y=2t^3

any help appreciated
2. t=2 given x=3t^2 Y=2t^3

dy/dx = dy/dt / dx/dt

dy/dx = 6t^2 / 6t
dy dx = 24 / 12 = 2
3. i was trying that but i forgot the you were supposed to put the t values in, as i thougfht it was supposed to be in trms of x. Thanks mate
4. no worries, good revision for me

After 1hour or 2 you probably be able to do parametric easily, at first i was just getting x and t muddled up for some reason
5. i need to redo the whole of c4 by tuesday, i learnt it from scratch about a month ago tried about 5 papers and wasnt getting anything below 80%, and now i cant remmber squat. I just pray everyting goes well
