Answer 3

You can. In some cases teh equation editor is not in the question box (something they wish to remedy at some point). However you can always use the "coding" of teh equations to do so. this coding follows LaTeX commands, but most people are not familiar with this.

One solution is taht you can open another open study window in your browser, and pretend to answer a question. Click on the equation editor button, and then construct your eqation, and then copy and paste the code for that equation that appears in the answer box when you hit "insert" and close the editor. Alternatively, if you google "online LaTeX equation editor" you will find numerous sites that will convert a constructed equation into LaTeX command format, which you can then paste into your question (remembering that you have to have the equation in between parenthesis (square or round, with a slash before each one i.e. "\ [y=x^{2}\] (with no spaces) which will give this \[y=x^{2}\] and it will always appear on a new line. Or if you use \ (y=x^{2}\) (again with no spaces) you get it to appear inline like this \(y=x^2\)
