Questions & Step-by-Step Solutions

Find the value of ∫ from 0 to 2 of (x^2 - 2x + 1) dx.
Correct Answer: 2/3
  • Step 1: Identify the function to integrate, which is (x^2 - 2x + 1).
  • Step 2: Find the antiderivative of the function. The antiderivative of x^2 is x^3/3, the antiderivative of -2x is -x^2, and the antiderivative of 1 is x.
  • Step 3: Combine the antiderivatives to get the complete antiderivative: (x^3/3 - x^2 + x).
  • Step 4: Evaluate the antiderivative from the lower limit (0) to the upper limit (2).
  • Step 5: Substitute 2 into the antiderivative: (2^3/3 - 2^2 + 2) = (8/3 - 4 + 2).
  • Step 6: Simplify the expression: 8/3 - 4 + 2 = 8/3 - 12/3 + 6/3 = 2/3.
  • Step 7: The final result of the integral is 2/3.
  • Definite Integral – The question tests the ability to evaluate a definite integral of a polynomial function over a specified interval.
  • Fundamental Theorem of Calculus – It assesses understanding of applying the Fundamental Theorem of Calculus to find the area under a curve.
  • Polynomial Integration – The question involves integrating a quadratic polynomial, which requires knowledge of basic integration rules.
