Not really the gradients are different whoch should be shown. They shouldnt look the same on the same graph although on a larger scale they could.

So you should squash and skew then.

Though without a few reference points, it mat still be far from exact!

Hello, I was hoping you could help with a query.

I'm revising Fp3 atm, specifically Hyperbolic. I have a question about graph sketching.

I'm aware that when you have one graph, accuracy isn't important. 1/x can look like 4/x as long as any asymptotes and axis crosses are denoted clearly. Is this the same when multiple curves are sketched in the same graph?

You need to make sure that the gradients are very roughly correct relative to each other. Any intersections with the axes, stationary points, horizontal or horizontal asymptotes should be in the correct order in roughly the right places relative to each other
Where one curve is higher than the other, this should be shown.

Thanks

Was meant to be horizontal or vertical asymptotes.

What modules are you doing?

FP2-4, M2, S2, STEP I-III.
I've also been self studying mechanics for STEP, so far done M3.

Oh okay! Have you been able to do any STEP Mechanics papers so far? :smile:

Most of the STEP I mechanics questions are straightforward, so I've been able to do a lot of them, but most of the STEP II-III mechanics questions need moments of inertia, angular momentum and related content. I understand the concepts, but don't know how to calculate these in practise yet. As such I've left most of the STEP II-III questions until later and am concentrating on the pure for now.

Oh okay. And you're planning on taking the papers next year, I presume. Year 12 then?
