# From Whiteboard to LaTeX in 3 Seconds: A Student's Workflow
|
|||
|
|
|
|||
|
|
If you've ever spent 20 minutes wrestling with `\underbrace`, `\overset`, or a nested fraction in LaTeX just to transcribe something your professor wrote in 10 seconds on a whiteboard — this workflow is for you.
|
|||
|
|
|
|||

|
## The Problem With Retyping
|
|||
|
|
|
|||
|
|
Retyping formulas by hand is slow, error-prone, and interrupts the flow of note-taking. A single misplaced brace breaks compilation. A wrong symbol — `\mu` instead of `\upsilon`, say — can change the meaning entirely. And some constructs, like large piecewise functions or multi-line aligned systems, take real LaTeX expertise to format correctly.
|
|||
|
|
|
|||
|
|
TexPixel removes all of this friction.
|
|||
|
|
|
|||
|
|
## The Workflow
|
|||
|
|
|
|||
|
|
### During the Lecture
|
|||
|
|
|
|||
|
|
Photograph each formula as it appears on the board. Don't worry about perfect framing — a quick phone shot is fine. A 150+ DPI photo taken under decent lighting gives TexPixel everything it needs.
|
|||
|
|
|
|||
|
|
You don't have to process anything during class. Just build up a folder of photos.
|
|||
|
|
|
|||
|
|
### After Class
|
|||
|
|
|
|||
|
|
1. Open TexPixel. Drag and drop the first photo.
|
|||
|
|
2. In under a second, you get LaTeX output — paste it directly into your Overleaf document or VS Code `.tex` file.
|
|||
|
|
3. Repeat for each formula.
|
|||
|
|
|
|||
|
|
For a typical lecture with 10–15 formulas, this takes about 2 minutes. Compare that to 20–30 minutes of manual retyping.
|
|||
|
|
|
|||
|
|
### For Homework
|
|||
|
|
|
|||
|
|
When working through problem sets:
|
|||
|
|
|
|||
|
|
1. Solve the problem on paper as you normally would.
|
|||
|
|
2. Take a photo of your work.
|
|||
|
|
3. Upload to TexPixel to extract the key formulas.
|
|||
|
|
4. Paste into your write-up.
|
|||
|
|
|
|||
|
|
This is especially useful for multi-step derivations where you want to show your work digitally.
|
|||
|
|
|
|||
|
|
## Exporting to Word
|
|||
|
|
|
|||
|
|
Not using LaTeX? If your professor requires Word submissions, use TexPixel's DOCX export. It produces native Word equations — not images — so you can still edit them in Word's equation editor after exporting.
|
|||
|
|
|
|||
|
|
## A Real Example
|
|||
|
|
|
|||
|
|
Here's a typical formula from a linear algebra lecture:
|
|||
|
|
|
|||
|
|
$$A = U \Sigma V^T$$
|
|||
|
|
|
|||
|
|
Manual LaTeX: `A = U \Sigma V^T` — straightforward, but you need to know `\Sigma` and `V^T`.
|
|||
|
|
|
|||
|
|
With TexPixel: photograph it, get `A = U \Sigma V^T` in one second, paste. For more complex expressions — a full SVD decomposition with summation notation and indexed entries — the time savings are even more dramatic.
|
|||
|
|
|
|||
|
|
## Tips for Lecture Photography
|
|||
|
|
|
|||
|
|
- **Position yourself centrally** — formulas at the edges of the board get distorted by perspective
|
|||
|
|
- **Wait for the professor to finish writing** — partial formulas confuse the parser
|
|||
|
|
- **Avoid flash** — it creates glare and washes out chalk or whiteboard markers
|
|||
|
|
- **Crop if needed** — if a photo contains multiple formulas, crop before uploading
|
|||
|
|
|
|||
|
|
## Building a Formula Library
|
|||
|
|
|
|||
|
|
Over a semester, you'll accumulate dozens of recognized formulas. Consider organizing them: paste each into a reference `.tex` file with a short comment. By exam time, you'll have a searchable personal formula sheet that took almost no effort to build.
