all the 2u/3u textbooks have good stuff on curve sketching.

the cambridge one has a "curve sketching template" which is like a guide...

i'll teach you!!

see...if you come up with an equation in the form of y=mx+b, u immediately say its a straight line with a constant gradient..hence where the m comes from!

haha thats pro. yeah, y = mx + b used to kill me in year 9

hmmm there are standard steps to sketch generic graphs.

1) whether the graph is odd / even (massive time saver)
2) asymptotes / intercepts
3) dy/dx, find all stat points.

there are more steps but u think for most cases thats all u need.
and keeping in mind that the graph can not cross the axes without either an intercept or asymptote, u can practically graph anything

having said that, i dont think in this regard there is much difference between math books, they essentially all teach u 'that', more or less.

 

[...]

drawing graphs just takes practice..like any other application i guess...

as Lobster said..intercepts, asymptotes and stationary/max/min pts are crucial to get the marks...

but also make sure ur graph co-response to the equation given(ie, correct function, +ve or -ve, is it a hyperbola or parabola or just a cubic curve etc...)

yeah, there's a whole prelim. topic "geometrical applications of calculus" i think...(well thats what my book says anyway).

theres a good komoroni book called "curve sketching" (what a title). we used it for 4 unit but its still good for 3unit. it explains everything and has fully worked solutions.

yeah, we have those booklets for 4u...but i'll tell there's enough stuff in the cambridge yr. 11 book for curve sketching-more than u need.
