In this paper, we look closely at the equation of the title, originally considered by Risch, which arises in the integration of exponentials. We present a minor improvement of Risch’s original presentation, a generalisation of that presentation to algebraic functions f and g, and a new algorithm for the solution of this equation. Full details of the last two are to appear elsewhere.
