Solution

Sure, here are the steps to evaluate the definite integral:

  1. Identify the integral: ∫sin(x) dx from π/3 to π.

  2. Find the antiderivative of sin(x), which is -cos(x).

  3. Apply the Fundamental Theorem of Calculus, which states that the definite integral of a function from a to b is F(b) - F(a), where F is the antiderivative of the function.

  4. Substitute π and π/3 into -cos(x):

    F(π) = -cos(π) = -(-1) = 1 F(π/3) = -cos(π/3) = -1/2

  5. Subtract F(π/3) from F(π) to get the result:

    1 - (-1/2) = 1 + 1/2 = 1.5 or 3/2.
