How to Use Integral in GeoGebra

All integrals are solved in the same way in GeoGebra. There are simple commands for finding both definite integrals and indefinite integrals. GeoGebra has also a command for partial fraction decomposition.

GeoGebra Instruction 1

Definite Integral

1.
Open CAS under GeoGebra icon View in GeoGebra icon Menu.
2.
Type

Integral(<Function>, <Start x-Value>, <End x-Value>)

in CAS. Fill in the expression you want to integrate as <Function>, the lower limit of integration as <Start x-Value> and the upper limit of integration as <End x-Value>. Note! The command works in Algebra View too.

GeoGebra Instruction 2

Indefinite Integral

1.
Open CAS under GeoGebra icon View in GeoGebra icon Menu.
2.
Type in the expression you want to integrate in CAS.
3.
Click on Integral GeoGebra icon . You get the indefinite integral in the same row.

GeoGebra Instruction 3

Partial Fraction Decomposition

1.
Open CAS under GeoGebra icon View in GeoGebra icon Menu.
2.
Type

PartialFractions(<Function>)

in CAS, and fill in the fraction you want to partially decompose as <Function>. Press Enter.

If you get the same answer as the one you inserted, then the fraction is already decomposed!
