Question

def sqrt(a):
def tryit(x):
return 0.5 * (a/x + x)
return fixedPoint(tryit(a), 0.0001)
This code has a bug in it. You can fix this by correcting exactly one line of the definition. Please do so in the box below.

Answer 1

what does fixedPoint() expect for its first argument?

Answer 2

If you try to create the framework around it and actually run the code, you will see that it complains about one of the arguments. It should be straight forward...
