• Example: Apart[(x^2 + 1)/(x - 1)] .
• Apart gives the partial fraction decomposition of a rational expression.
• Apart[ expr , var ] writes expr as a polynomial in var together with a sum of ratios of polynomials, where the degree in var of each numerator polynomial is less than that of the corresponding denominator polynomial.
• Examples: Apart[(x + y)/(x - y), x] .
• Apart[(x + y)/(x - y), y] .
