Click here for examples to see how special symbols are used. Examples are accompanied by source code and are rather self explanatory.

  • Sums are entered using a "sum" function
 sum( from, to, expression )   <-- sum with limits
 sum( expression )             <-- sum without limits


 e=sum( i=0, N, 1/i! )
 sum( 1/i ) = infinity
