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
CAS     under         View     in         Menu.         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
CAS     under         View     in         Menu.         CAS.         Integral 
      
     GeoGebra Instruction 3
CAS     under         View     in         Menu.         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!
