Summing up series

To calculate a partial sum of a series, switch MathMate into Summation mode. Then the entry fields for the summation limit appear.

Using this operation you are able to calculate partial sums of series with the given term when the summation variable takes values within the given limits. On every step the summation variable is incremented by 1 and the value of the expression is added to the result if the summation variable does not exceed the upper summation limit. Summation variable and limits may take non-integer values.

To calculate a sum:

  1. Switch the Summation mode on
  2. Input an expression, e.g. 1/x
  3. Input the summation limits
  4. If the expression contains several identifiers point out which one is assumed to be the summation variable.

  5. If MathMate detects only one parameter in the expression that has not been assigned a value and no parameter has been declared variable, this parameter is taken as summation variable. If all the parameters have been assigned values, the sum term is considered constant.
  6. Initialize the other parameters
  7. Click Start or press Enter
