How do I put math symbols in pdf files? In Typeable Pdf Typeable Pdf or reader, theres a tool to put sticky notes onto the text. I can make small notes, and I can add math symbols by copying and pasting them from wikipedia. is there any way I can actually type math symbols instead of copy and paste?

How do I do this? Xc = 2πfC I'm using Unicode characters, which also enable me to do this. 我喜歡中文 or Я говорю русский плохо. Most computers support unicode now. I use a Mac which makes it pretty easy to enter using the "keyboard input sources". If you have a Mac, go to System Preferences -> Keyboard -> Input Sources and 1) select the "Show Input menu in menu bar" checkbox and 2) if you want a foreign language entry method, add a language entry method. For Chinese I use "Pinyin - Traditional", for Russian I use "Russian - Phonetic" plus the default for "US English". For some characters you can enter them directly from the keyboard using the "Alt/Option" button and a regular key or key sequence. You can get a visual hint/view of these when you go to the Input Menu you enabled and select "Keyboard Viewer". With this you can do "i = √-1" with "alt-v" for the √ symbol. I can do German umlaut-u with "alt-u u". Herr Müller! Wie gehts? That's also how I do "Schrödinger's Equation applied to a 20Å gate oxide" at full touch-typing speed! For other symbols that aren't directly key-able, there's the "Character Viewer". Here you can browse or search for characters. When you see one you want you can cut-and-paste or simply double-click (it will drop the character into the window you have in focus at the current cursor location). Here's "Math Symbols". This gives you Maxwell's Equations. ∇E = 𝜌/ϵ, ∇B=0, ∇×E = -∂B/∂t, ∇×B=µ(J+ϵ ∂E/∂t). You can also search, for example, if you want "Omega". R = 2.5KΩ. You can't create ALL math equations with unicode but if t are in-one-line you can do quite a bit! Still you probably want to use LaTeX or MathML or MS Word for "full feature typesetting quality" math. I assume Windows or Linux can do similar - I've never needed to learn them however.

PDF documents can be cumbersome to edit, especially when you need to change the text or sign a form. However, working with PDFs is made beyond-easy and highly productive with the right tool.

Type on PDF: All You Need to Know

If you don't know LaTeX, you'll probably find it very much fun to learn! I just learned to code in LaTeX recently, so I'm learning that, as well. I'm going to write this one, so that it's very brief. I have tried to explain some ideas and explain some math concepts for you to try. Furthermore, I will leave some of it out for brevity. I'm sure there are going to be questions, so if you have a question or comment (I'm sure it will be in the comments) I'll try to answer it here. You can e-mail me at: Schneller at or the Google+ Group.
