Step 1: Understand that we want to find the integral of sin(x).
Step 2: Recall that the integral of a function gives us a new function whose derivative is the original function.
Step 3: Remember the basic rule for integrating sine: the integral of sin(x) is -cos(x).
Step 4: Add a constant 'C' to the result because integrals can have many functions that differ by a constant.
Step 5: Write the final answer as -cos(x) + C.
Integration of Trigonometric Functions – This concept involves finding the antiderivative of trigonometric functions, specifically the sine function in this case.
