The action can be expressed as d dx ±Z f ( x ) dx ² = f ( x ) Z F ( x ) dx = F ( x ) + C. Indeﬁnite Integrals of Basic Functions (a) Z x n dx = x n +1 n + 1 + C (b) Z e x dx = e x + C (c) Z 1 x dx = ln | x | + C (d) Z kf ( x ) dx = k Z f ( x ) dx for any constant k , (e) Z [ f ( x ) ± g ( x )] dx = Z f ( x ) dx ± Z g ( x ) dx 2 Example 4. Find each indeﬁnite integral: (a) Z 2 dx (b) Z 16 e t dt (c) Z 3 x 4 dx (d) Z (2 x 5-3 x 2 + 1) dx (e) Z ± 5 x-4 e x ² dx (f) Z ± 2 x 2 / 3-3 x 4 ² dx 3...
