###### Question details

This is an actuarial science course, centered around life contingencies (survival models and such). We are supposed to use other actuarial equations of mu_x to help prove, such as Var(T_x) = 2 * integral from (0,∞) of (t * S_x(t))dt - integral from (0,∞) of S_x(t)dt and E[T_x] = integral from (0,∞) of t_p_x dt I believe.
