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