Question

Determine the following integrals:

  • Note, in particular, that integration ‘by inspection’ (i.e., writing down the answer and differentiating it to show that it is correct) is not a valid method in answering the question.
  • You may quote without proof the formula for integration by parts, and the formula for integrals of the form ∫ f ′ (x)/f(x) dx, but, if used, your working should include an explicit statement of the formula the first time it is used in each question. If a particular formula is required more than once in a given question, you should also explicitly mention the formula each time it is used subsequently (e.g., justify a subsequent step in your argument by saying “...using the formula for integration by parts”)
  • You may assume, without ever mentioning, the linearity property of the integral
  • Note that you may not assume without proof any other integrals.
