Dx in integration
WebIntegration By Parts Formula If u and v are any two differentiable functions of a single variable x. Then, by the product rule of differentiation, we have; d/dx (uv) = u (dv/dx) + v (du/dx) By integrating both the sides, we get; uv = ∫u (dv/dx)dx + ∫v (du/dx)dx or ∫u (dv/dx)dx = uv-∫v (du/dx)dx …………. (1) Now let us consider, WebExample: What is2∫12x dx. We are being asked for the Definite Integral, from 1 to 2, of 2x dx. First we need to find the Indefinite Integral. Using the Rules of Integration we find that ∫2x dx = x2 + C. Now calculate that at …
