Guide to Using the TI-Nspire for SPECIALIST – The intricate and tightly packed

Wow thanks, never knew the expand tool gave you partial fractions.

Do you know if there is any way to use the 3D graphs to somehow plot vectors with i,j & k? For example, showing what i + 2j - 3k would look like? I was trying to figure this out hmm...

I don't think it is possible. I found how to do 2-d vectors, but it takes a lot of time, but good to check say you vectors for a parallelogram e.t.c

Ah okay - they'll probably include it in a later version when we've all finished...

Small update to Version 1.01 to add the magnitude of a vector.

UPDATED to Version 2.00 to include sketching circles, elipses and hyperbolas in one step. Thanks to vgardiy for how to do it.

^^Did not know that one! Good tip!

Yeh I didn't either until vgardiy pointed it out in the methods thread. Does make life easier doesn't it.

Thanks for this, extremely useful!

No problem, and if anyone else finds anything useful let me know. (Plus I probably should have added the finding the inverse function thing).

I should probably add that to highlight text, you use CAPS left/right, not ctrl. Otherwise, great work!

Ah, thanks for that. I was confused as to why I couldn't highlight text after upgrading the OS. I was trying to figure out how to do it for ages haha.

Which part of the guide is that under?
NVM: Found it, sorry guys, the buttons are close. I'll fix it in the post and make a note to fix that in the prinatble version.

Hey I need some help with parametric graphing please; whilst trying ti use the parametric graphing thing; I'm not getting a very clear image of what the graph is supposed to look like: The equation I used was: r(t) = (2/(t-1))i +(4/(t+3))j. It also states in the question that t>5; so how do I input this properly to get a clear graph?

[b^3]

Ok this doesn't look like it works too well, but I'll give it my best shot here.
in x(t) you should have 2/(t-1)
in y(t) you should have 4/(t+3)
underneath that you need to cahnge the 6.28 to a 5.
It draws a horizontal line at y=1, which is an asymptote (I had to check it manually).
I;m not 100% sure if the t>5 rstriction worked though.

For this one I think it is better to do it manually so that you don't encount any errors as a result as the calc. sorry I can't really help.

Ah darn; still, thanks for the reply, I appreciate it + all the other tips in your guide
