# List of functions used for infinitesimal approaching.
# An item in this list will be picked randomly at each exercise.
# Structure of item: multi-line.
# line 1 is function description.
# line 2 is x_0.
# line 3 is order function.
# The rest is values for parameters c1, c2, etc.
# Different items are separated by lines starting with `:'.
