1. T : Type
2. f : T

T
3. m : T

4.

x:T. m(f(x))

m(x) & (m(f(x)) = m(x)

f(x) = x)
5. x : T
6.

n:

. m(f^n(x))

m(x)-n

f(f^n(x)) = f^n(x)
7. m(f^m(x)+1(x))

m(x)-(m(x)+1)

f(f^m(x)+1(x)) = f^m(x)+1(x)

f(f^m(x)+1(x)) = f^m(x)+1(x)

By:	Analyze -1 THEN Try Trivial

Generated subgoal:

1 7. m(f^m(x)+1(x))m(x)-(m(x)+1)
f(f^m(x)+1(x)) = f^m(x)+1(x)
