Question #5e856

Answer 1

Here's what you can do.

Explanation:

To add the q.e.d. symbol to the Socratic edit, write it in Microsoft Word using Unicode, then copy/paste it in the answer in between hashtags.

So, I wrote the q.e.d. symbol in Word and got this

▄

If I use hashtags

hashtag ▄ hashtag

I will get

`▄`

Now just use it anytime you want. To take an example you used in one of your answers, you will have

`csc(x)-sin(x) = cos(x)cot(x) rArr`

`1/sin(x) - sin(x) = cos(x)*cos(x)/sin(x) rArr`

`[1/sin(x) - sin(x) = cos(x)*cos(x)/sin(x)]*sin(x) rArr`

`sin(x)/sin(x) - sin^2(x) = cos^2(x)*sin(x)/sin(x) rArr`

`1 - sin^2(x) = cos^2(x) rArr`

`sin^2(x) + cos^2(x) = 1` `▄`

The alignment is not perfect, but I think it gets the job done.

Answer 2

You can also add, within the hashtags:

hashtag " "" "" "" "" "" "square hashtag

Basically, it's a string of " " units next to one another, which creates space, and then square, which when between hashtags makes a `square`.

Within the context of a problem, this could look something like:

Hence `T-r_i={m+k+1-r_i,...,m+r+r_i}` is a segment of length at most `r-k < r` of `B_0`. Since `m+k+1-r_i < m`, this contradicts the definition of `S". "" "" "" "" "square`
