Using LibreOffice or most other word processors and some text editors,
it is possible to copy and paste the
Ω symbol and other mathematical
symbols into EasyEDA text both here in the editor and in Forum posts.
the integral symbol:
the Sigma symbol:
and several more:
∂, ∆, ∏, √, ∞, ≈, ≠, ≡, ≤, ≥ and so on
Insert > Special Characters > Subset > Mathematical Operators
Trigonometrical and other symbols such as:
π, δ, ε, θ, λ, μ and so on
Insert > Special Characters > Subset > Basic Greek
However, please note that the tilde symbol is a reserved character in EasyEDA and so cannot be entered into text in a schematic.
If the formula is more complex and needs to be clearly represented in a formal mathematical format then it can be entered into the Formula Editor of LibreOffice (or some other word processor), saved as a .doc or .docx file and then uploaded into your projects page in:
as an Attachment like the
Mathematical_examples.docx files attached to this project.
If you can convert (export) the formulae from the Formula Editor into a .jpg or.png image then you can save it somewhere and upload it as a project page Cover image as show above.
Once uploaded, right click on the image and do:
Copy image address
You can also then link the image into a schematic using the Image button on the Drawing Tools palette:
and then selecting the image region and entering the URL (the image address you just copied from your project page Cover image) into the right hand Properties panel:
Then position and resize the image as required:
However, it may take several attempts to get the right image resolution using this approach.
