Questions & Step-by-Step Solutions

Find the value of ∫ from 0 to 1 of (x^3 - 3x^2 + 3x - 1) dx.
Correct Answer: 0
  • Step 1: Identify the function to integrate, which is f(x) = x^3 - 3x^2 + 3x - 1.
  • Step 2: Find the antiderivative (indefinite integral) of f(x). This means we need to integrate each term separately.
  • Step 3: Integrate x^3 to get (1/4)x^4.
  • Step 4: Integrate -3x^2 to get -x^3.
  • Step 5: Integrate 3x to get (3/2)x^2.
  • Step 6: Integrate -1 to get -x.
  • Step 7: Combine all the results from Steps 3 to 6 to get the antiderivative: (1/4)x^4 - x^3 + (3/2)x^2 - x.
  • Step 8: Now evaluate the antiderivative from 0 to 1. This means we will calculate the value at x = 1 and then subtract the value at x = 0.
  • Step 9: Calculate the value at x = 1: (1/4)(1)^4 - (1)(1)^3 + (3/2)(1)^2 - (1) = 1/4 - 1 + 3/2 - 1 = 0.
  • Step 10: Calculate the value at x = 0: (1/4)(0)^4 - (1)(0)^3 + (3/2)(0)^2 - (0) = 0.
  • Step 11: Subtract the value at x = 0 from the value at x = 1: 0 - 0 = 0.
  • Step 12: Therefore, the value of the integral from 0 to 1 is 0.
  • Definite Integral – The question tests the ability to evaluate a definite integral of a polynomial function over a specified interval.
  • Polynomial Integration – It assesses knowledge of integrating polynomial functions and applying the Fundamental Theorem of Calculus.
