curve sketching question ^^ (1 Viewer)

[Grey Council]

no no, im not confused.

AARGH! I'm leaving this to the curve experts. I think i'll stick to complex numbers. I haven't even done curves yet.

yes yes..that's right...kinda..
in the answer:

- never goes above 1, or below -1
- bell shaped curve thing
- cuts y at (0,1)
- cuts x at +-1
- asymp at y = -1
- inflex at (-1/sqrt of 3, 1/2) and 1/sqrt of 3, 1/2) <-------- this is wht i can't find..=(

what is that

 

[Xayma]

MATLAB is a graphing program used by universities.

 

[Grey Council]

for some reason people here want it to use for graphing.

just get graphamatica, its good enough for all but hte hardest 4u questions.

u can try do the questions on Terry Lee 4unit maths book
the curve sketching questions are very good there
way better than the ones in the cambridge4u

however, dont do the conics part in Terry Lee book, some concepts are not well expressed, use cambridge 4u for conics

curve sketching is actually all about practice
