This tool can be used to rotate any graph on Desmos (and most other software) by a certain angle.
- Go on Desmos and create a new slider for variable "a" that ranges from 0 to 2pi. (You don't need to type the pi symbol just type "pi")
- Go on the app.
- If you have the graph equation copied, just click "Convert Clipboard". Otherwise, type the equation in the textbox and click "Convert Text".
- Click "OK" in the popup window.
- The rotatable graph equation is now in your clipboard.
- Go on Desmos again.
- Paste the equation into a new item.
- And you are done! You can now use the slider to rotate the graph at any angle.
- Always use parenthesis in functions. (type "cos(2x)" instead of "cos2x")
- Include what the expression should be equal to (even if its just y) at the end of equations. (type "4x + 3 = y" instead of "4x + 3")
- Not following these tips might cause the app to work incorrectly.

I'm not a good mathematician nor a good programmer so the app might have some bugs.
