The Function aplet is probably the one that you will use

! graph equations
find intercepts
!
! find turning points (maxima/minima)
! find areas under curves
! find areas between curves
! find gradients
! find derivatives algebraically
! find simple integrals algebraically
evaluate functions at particular values
!
! graph and evaluate algebraically expressions such as f(g(x)) or f(x+2)
