How to embed figures
 11:38 WIB

For the time being there is no space provided for the figure files in the WoPhO server. If  the physics problem you are about to submit requires some figures, here are several things you can do 

  1. Upload the figure file(s) to any free image hosting server. 
  2. If you have a google account, you can upload the figure file(s) to google docs. Set the sharing settings to public. 
  3. Copy the url address of the figure. For google docs you can do this by right clicking the figure then choose "copy image address".
  4. In the submit problem form, click the add image icon. Then paste the url address you have copied




How To Embed Mathematical Symbols
 10:22 WIB

Mathematical formulas are rendered using mathTeX. 

Familiarity with LaTeX  is required. The following example shows how to embed mathematical symbols using LaTeX. To create inline math, use standard LaTeX delimiters with mathematical expressions sandwiched between two dollar signs. For display-math mode, use two pairs of dollar sign:


The speed of sound in a medium with bulk modulus $B$ and density $\rho$ is given by
$$v=\sqrt{\frac{B}{\rho}}$$

with the following output:


The speed of sound in a medium with bulk modulus $B$ and density $\rho$ is given by 


$$v=\sqrt{\frac{B}{\rho}}$$ .
