Statement 1: If both functions `f(t)a n dg(t)` are continuous on the closed interval [a,b], differentiable on the open interval (a,b) and `g^(prime)(t)` is not zero on that open interval, then there exists some `c` in `(a , b)` such that `(f^(prime)(c))/(g^(prime)(c))=(f(b)-f(a))/(g(b)-g(a))` Statement 2: If `f(t)a n dg(t)` are continuous and differentiable in [a, b], then there exists some `c` in (a,b) such that `f^(prime)(c)=(f(b)-f(a))/(b-a)a n dg^(prime)(c)(g(b)-g(a))/(b-a)` from Lagranges mean value theorem.
