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 Integrals

1.: Open CAS under View in Menu.
2.: Type

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

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

GeoGebra Instruction 2

Indefinite Integrals

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

GeoGebra Instruction 3

Partial Fraction Decomposition

1.

Open CAS under

View in

Menu.

2.

Type

PartialFractions(<Function>)

into 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!
