Solution Summary
Linear Functionals, Continuous Derivatives, Vector Spaces and Scalars are investigated.
Solution Preview
the differentiation and integration operators are linear
the squaring operation is not linear, and neither is the integral of the square of f(t)
// take int_a^b to mean the integral from a to b //
then int_0^1 t^2 f(t) is a linear functional, since f is unaffected
int_1^2 f(t^2) dt = int_1^4 f(u) du which is ...
