full marks?
I'm getting a solid 1 maybe.

this is the graph btw

worst part is 1 mark is probs proving y>=xtanx, then 1 for all intercepts and 1 for shaded correctly

 

[idkkdi]

did we need to use arctanx to get full marks i just used inverse tan (tan^-1 x)

oh , ye nah.
hsc isn't that mean.

 

[Trebla]

I was talking about the mechanics question lol

 

[Siwel]

oh , ye nah.
hsc isn't that mean.

i was gonna say just completely ignored their arctanx and its a show that q was about to fume..., the feeling of realising something so stupid after the exam

 

[Siwel]

If you download the Extension 1 and 2 syllabuses and search for the work arctan, all that pops up is "not found".

Could be a problem.

What? That sounds even more complicated. Can you draw it rather than me trying to interpret your comments and then drawing it wrong.

look i can but its gonna be on a paint.net kinda thing soooo its gonna be kinda shocking

 

[tywebb]

doesnt include real and imaginary as a line so should be one extra past a+ib and one going negative tanx like for memory

wait this is more correct.
it was 20 lines iirc.
I'm missing a few lines.

yeah all ik is when you choose a point go 4 between and eventually you end up the same spot

what you reckon the hardest question in that exam?

 

[idkkdi]

what you reckon the hardest question in that exam?

perhaps the very last one.

any more thinking about that 4u test gonna give me depression. cya.

 

[tywebb]

So 20 lines like this?

 

[tywebb]

If that is the case then the answer is like this:


Was there something a bit more specific about the modulus of a+ib in the question?

nope nothing more, just guessed honestly had no clue how to do without numbers, except mod>1 obv

 

[Siwel]

would you think mark for realising 4 lines between answers?
