# 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.
