Questions and Answers

What is the result of integrating 2sin(2θ) with respect to θ?

  • −2(1 − cos(2θ)) + C
  • −2θ + sin(2θ) + C (correct)
  • −2tan(θ) + C
  • −2θ + cos(2θ) + C
  • What is the formula for integration by parts?

  • ∫udv = u∫vdx + ∫v∫udx
  • ∫udv = ∫uvdx - ∫vdx∫udx
  • ∫udv = uv - ∫vdu
  • ∫udv = u∫vdx - ∫dv∫udx (correct)
