# 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

### DefiniteIntegral

1.
Open `CAS` under  `View` in  `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

### IndefiniteIntegral

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

`GeoGebra` Instruction 3

### PartialFractionDecomposition

1.
Open `CAS` under  `View` in  `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!
