Calculate ∫ from 0 to π of sin(x) dx.

Correct Answer: 2

Step 1: Identify the integral you need to calculate, which is ∫ from 0 to π of sin(x) dx.
Step 2: Find the antiderivative of sin(x). The antiderivative is -cos(x).
Step 3: Evaluate the antiderivative at the upper limit (π): -cos(π) = -(-1) = 1.
Step 4: Evaluate the antiderivative at the lower limit (0): -cos(0) = -1.
Step 5: Subtract the lower limit result from the upper limit result: 1 - (-1) = 1 + 1 = 2.
Step 6: Conclude that the value of the integral ∫ from 0 to π of sin(x) dx is 2.
