Substituting series expansions into each other

Consider the formal power series f(x) = x + x^2/2 + x^3/6 + x^4/24 and g(x) = x - x*/2 + x^3/3 - x^4/4. Compute by hand the first five coefficients (i.e., up to the coefficient of x^4) of (a) h(x) = x^f(x) (d) k(x) = log(1 + g(x)) (c) m(x) = (h o k)(x)

In what ways can the cycle of inequality be broken in schools?

Savage Inequalities is a wonderful book to reference here as it does point to the problem of inequitable funding. In other words the poor stay poor because the school is funded disproportionally from community to community. This then impacts society's views of certain minorities and the poor, but then it also continues to fuel t
