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
CAS
under View
in Menu
. Sum(<Expression>, <Variable>, <Start Value>, <End Value>).
Type the expression for in <Expression>
. Type for <Variable>
. Insert the start value of in <Start Value>
, and the end value of in <End Value>
.
If you want to compute an infinite series, type inf
in <End Value>
(inf
is short for infinity).
