Questions & Step-by-Step Solutions

Determine the area under the curve y = 1/x from x = 1 to x = 2.
Correct Answer: ln(2)
  • Step 1: Identify the function we are working with, which is y = 1/x.
  • Step 2: Determine the limits of integration, which are from x = 1 to x = 2.
  • Step 3: Set up the integral to find the area under the curve: ∫(from 1 to 2) (1/x) dx.
  • Step 4: Find the antiderivative of 1/x, which is ln(x).
  • Step 5: Evaluate the antiderivative at the upper limit (x = 2) and the lower limit (x = 1): ln(2) - ln(1).
  • Step 6: Simplify the result. Since ln(1) = 0, the area is ln(2) - 0 = ln(2).
  • Definite Integral – The question tests the understanding of calculating the area under a curve using definite integrals.
  • Natural Logarithm – The solution involves the natural logarithm function, specifically evaluating ln(x) at given bounds.
