    📖 Beginner's guideHow to Solve a Definite Integral (Power Rule)Learn what a definite integral means, how to find the area under y = xⁿ with the power rule, worked examples, and a free calculator with step-by-step answers.

    Worked Example: Definite Integral (Power Rule)

    Given:

    • n = 2
    • a = 0
    • b = 2
    1. ∫[0 to 2] x² dx = [x³/3]|[0 to 2]
    2. = (2³/3) - (0³/3)
    3. = 8/3 - 0
    4. = 2.67

    Answer: 2.67
