The definite integral \( \displaystyle\int_{a}^{b} f(x)\,dx \) is defined as the limit of

  • A.the difference of the function's values at the two limits
  • B.the derivative of the function averaged over the interval
  • C.a product of the function's mean value and its derivative
  • D.a sum of areas of thin strips as their width tends to zero

Answer: D

The Riemann definition partitions the interval, forms \( \sum f(x_{i})\,\Delta x_{i} \), and takes the limit as the largest width tends to zero. That the result equals \( F(b) - F(a) \) is the content of the fundamental theorem, a proved connection rather than the definition itself
