After the update with swipe button pad

Contradel

After the update with the swipe button bad, I cannot pinch to zoom graphs while under the move tab, is this meant to be removed?

Also how about a favorites tab, like if you swipe two times down or something, you could define your own shortcuts and maybe see favorited commands from the catalog. like I would love to have f(x) and g(x) as a shortcut
For example. However I must admit the implementation of the swipe to controlling copy and paste is pretty cool.

Wait.. Where is the single [ button and the single ] button?
And how do I go one digit forth? The -> button goes all the way right and then changes to new line symbol.

If you click on the [...] button and input a list of numbers and then press -> it will take you one digit forward, press it again and it takes you to the end of the line. Just using the -> arrow once in general will take you to the end of the line.

The behavior is designed so that if you want to input a list, you just press the [...] button, input the list, and then press the -> to keep writing.

If you want a single [ or ], just use [...] with the backspace, or [...], ->, backspace.

I don't think too much about it at this point, but now that I've written this kind of directions out it does seem a little much to do; would it help to have a separate button for the single [ and ]?

Well sometimes when writing math in free hand you would add () after you entered some math, when you realize it would only work that way. So I guess if you want to approach normal inputting where you can't think the whole equation through before typing, two dedicated buttons for () and [] as well would be preferable. That is at least my argument, as I find myself forgetting to add () or [] before.

Hey also. I walked into this nasty bug, I wanted to solve something really simple, an intersection between

Solve(2*sqrt(x)=1/2x,x)
And it returns
[0, ...]

Where a solution would be 16, which it also finds with intersection through the graph. So I can imagine these very specific bug reports are cumbersome to get, because it's probably somewhere down deep in the core, but I wondered if you could shed some light why it says "..." in the solution field?

Thanks for the response though.

Another thing you can do is highlight some text and then press () or [], and it will insert them around the highlighted text.

It returns [0,...] because 0 is a solution and there may be more. If you add another argument, say Solve(2*sqrt(x)=1/2x,x,10), then it uses Newton's method to converge to a solution, so it will return 16. In general solving an equation is tricky business.

I believe if it can't solve the equation analytically, it uses 1 as an initial guess for Newton's method, hence the [0,...]. It is saying that it found one root, and that there may be more.

How do I highlight text? I'm on the iPad.

Ah okay. So if it would return [..., -3] the other answer(s) would be below -3, and I'd have to add , -10 in the end? I tried a bunch of numbers, and Solve(2*sqrt(x)=1/2x,x,4) returns
4
Which doesn't seem to add up, did I do something wrong?

However if I add the interval:

Solve(2*sqrt(x)=1/2x,x,[-100,100]) It returns
(0, 16)
:-) and I'm happy. But I'm thinking that if it detects more solutions possible, isn't there enough processing power in these devices to automatically try some intervals, I see there would be a problem if there's infinite solutions, yea okay it is tricky business, probably more tricky than I can imagine.

The pinch feature will be fixed in the next update. It just got broken in this latest release.

Howdy, Stranger!
