HOW CAN I ITERATE THIS PDE IN THE FORM OF PICARD ITERTION.

ATTACHED IS THE MAPLECODE  STARTED WITH.

Hello

    IS THERE ANY MAPLE CODE FOR SOLVING SYSTEMS OF ODEs using IMPLICIT RUNGE KUTTA SUCH AS LOBATTOIIIA,LOBATTOIIIB and LOBATTOIIIC.THANKS

PLEASE HELP OUT

  I try to loop this problem using if statement but i am getting wrong lobatooB.mwaswer,the works looks like this see the attached file
