(71B) Euler-Taylor method for the HP-71B

[Csaba Tizedes]

Hi Namir, just two comments:

1.) at relative error calculation the divisor is Y0 not 10, I guess
2.) I am not familiar with 71B, but in the function definitions there is not important the case sensitivy (y or Y)?
+1) you know that, there is a cheating when you defined the second derivative, I mean a differentiation procedure is required, because thats why we use computers...
