• Equation editor: Science, especially physics and math is not complete without equations and the ocean of signs and symbols. For this, there is a real time equation editor in LaTex. Click on the link “Visual equation editor” and paste the LaTex code in your opinion. You can use the LaTeX from the editor on Function Space by putting it between '$' signs. Please see "How to render LaTeX equation?" for more details. • Equation caller: While writing a known equation, instead of writing the entire equation, just type “: equation name” and the equation caller will give you the entire equation. All this will be done without any line of code. • Diagramming tool: In built Diagramming tool for making diagrams, flow charts and networking models. • Markdown formatting • Render LaTeX equation: Put your LaTeX code between '$' sign and see the live preview of the equation on right side of the screen (See the example below). For getting LaTeX code, see Equation editor and Equation Caller.
• Image posting: You will need to upload your picture on one of the free image hosting websites. Click on ‘Image’ button on the tool bar and paste pic's hyperlink in the toolbar. Maintain the appropriate image size (preferred 600 x 300) for better readability.
