Types two hours of latex in solution, clicks away from the problem box, loses all text.

@John Muradeli @Agnishom Chattopadhyay This is definitely very inconvenient, and we are planning to improve this behavior. However, it might take us a while and in the meantime, if you will be writing a long Latex solution, you could use a preview program like www.writelatex.com.

Hey, thanks for the link! But here's what I get:

This is from my school computer which has administrative settings that block lots of things, so could be due to that. If I do it from home, it may be different. Meanwhile, I wonder if anyone else has such issues.

There was an extra dot (.) added after the url. If you remove the dot or click on the link (I converted the url from text to a link) it will probably work.

@Sam Solomon Ooh woah what a dumb mistake.

Thank you!

(btw your edit's link is broken)

@John Muradeli Haha, of course I would make that mistake... Fixed it.

Sorry, I can't see the 3D Version there. If you can get an image of it please tell me, I will consider using it in my Valentine's day card.

In the meantime, I created this using complex_plot: Link

@Agnishom Chattopadhyay OMG that's amazing!!!

Is it only possible on that website or can I use some other more convenient software to do it?

Oh and 3D I was referring to one of Wolfram's 3 variable equations where they advertised Valentine's Day discounts or something... But I think it plots not as cool as they advertise, but WOAH your heart is the epitome of 2D hearts :O

@John Muradeli I did it with SAGE

You can run sage on the cloud with this

Just copy and paste the following code:

1
2
3
4
5
6
def f(z):
    x = real(z)
    y = imaginary(z)
    return (x^2 + y^2 -1)^3 - x^2*y^3

complex_plot(lambda z: (1/f(z)*i^(z+1)),(-1.5,1.5),(-1.5,1.5),plot_points=50)

Edit the plot_points=50 line if needed for a better resolution

@Agnishom Chattopadhyay I actually get a pretty crappy quality with 50. Are you sure you used 50 and not 500? Or it could be my computer. So I basically kinda get it, but what's up with all the lambda z and 1/f(z) and stuff? Is this some computer programming jargon?

@John Muradeli I used 300 or 500 but I suggested 50 because it is quicker.

f(z) has been defined in the code already. lambda is a programming jargon. It is just an way of writing a function without giving a name to it

I suggest typing your solutions on word or something rather than brilliant.

When I work with Latex I must occasionally click preview to see if I've fixed everything, and this is when my computer can lag and I'll click in a space below the problem box and then I lose everything. Thankfully I anticipated this happening and had the code pasted in an empty tab, though I did have to recover about 20 mins of work that I did not copy at the time.

Still, Brilliant needs to fix this. Imagine if I didn't save that thing? I'd go MAD!

@John Muradeli I think the best you can do at present is to copy it on the clipboard constantly. I do this, so if I accidentally click on 'back', I can still go back and click on 'paste'...

@Satvik Golechha Some times I have to copy other sections of the text within the latex (like those that repeat frequently, ex. cuberoots and fractions and stuff), and forget to copy the whole thing... Besides I shouldn't be feeling like I'm on tip-toes on this. The text should remain even if I click away.

But for now, copying repeatedly will do.
