How to Use the Sum Command in GeoGebra for Sums and Series

Use GeoGebra to calculate sums, including infinite series. These are a lot of work to compute by hand, but GeoGebra makes it easy.

GeoGebra Instruction 1

1.
Open CAS under GeoGebra icon View in GeoGebra icon Menu.
2.
Use the command

Sum(<Expression>, <Variable>, <Start Value>, <End Value>).

Type the expression for an in <Expression>. Type n for <Variable>. Insert the start value of n in <Start Value>, and the end value of n in <End Value>.

If you want to compute an infinite series, type inf in <End Value> (inf is short for infinity).
