Integrating standard functionsExam-style questions

The integrals you get by reading the derivative table backwards — e^x, sin, cos, sec² and 1/x. Why a linear inside, such as e^(3x) or cos 2x, means dividing by its coefficient; the signs on sine and cosine; why 1/x integrates to ln|x|, modulus included; reciprocals of linear functions; and exact values when these appear in definite integrals.
