Yes sure, first choose a label then key in:
1(one)
sqrt(x)
/(divide)
rtn(return)

Then run the integral function between 0 and 1

Answer should give 2 in a matter of seconds.

Cheers and I hope this helps

Your code gives 0.5, because I believe you need to insert X<>Y between 1 and sqrt(x). In FIX 2 the modified program gives 1.99. In Fix 3, the modified program gives 1.999, and so on.

The code I used is one step shorter:

Code:


LBL A
sqrt(x)
1/x
RTN
