Maxima Function
risch (expr, x)
Integrates expr with respect to x using the
transcendental case of the Risch algorithm. (The algebraic case of
the Risch algorithm has not been implemented.) This currently
handles the cases of nested exponentials and logarithms which the main
part of integrate can't do. integrate will automatically apply risch
if given these cases.
erfflag, if false, prevents risch from introducing the erf
function in the answer if there were none in the integrand to begin
with.
