There was a symbol with an o with a dash through it sort of like this O. Does anyone know what it means?

        Hi @The-Darkin-Blade,

        This symbol \(\theta\) is a letter from the Greek alphabet that is called theta. In this alphabet there are also the letters \(\alpha,\) \(\beta,\) \(\gamma,\) \(\pi,\) \(\Sigma,\) \(\Delta,\) and many more. Mathematicians and other scientists use the letters from the Greek alphabet to label different objects or actions in math or science: it could be angles (\(\alpha,\) \(\beta,\) \(\gamma,\) ...), the sum of repetitive objects (\(a_1+a_2+...+a_n = \Sigma_{i=1}^{n} a_i,\)) the abstract small number \(\epsilon,\) or many other helpful things 🙂

        In that particular case, the symbol \(\theta\) was used just as a label for an angle, like any other symbol, such as \(\alpha,\) \(\beta\) or \(\gamma,\) that we use to label the angles in geometry.

        Here is a Greek alphabet:

          @nastya Thank you! It really helped (and helped me with science too)!

              @nastya Do you have a list of each Greek letter's uses? That would be very helpful.
