∫ edx = ∫ e aSubstitution of (1) and (3) in the given integral. ax b. u du ∫ e du= 1. a. u. e c= 1 u. a = e. ax b. a c. We compare this integration with ∫ x dxIn the same way by taking the linear function of x as u or u = a x + b we can establish. all the ten extension formulae. Example 4. Find ∫ (2. x ................
