Step 1: Understand that we want to find the integral of the function cos(x).
Step 2: Recall the basic rule of integration for trigonometric functions.
Step 3: Remember that the integral of cos(x) is a known result.
Step 4: The integral of cos(x) is sin(x) plus a constant (C) because integration gives us the original function plus a constant.
Step 5: Write down the final answer: The integral of cos(x) is sin(x) + C.
Integration of Trigonometric Functions – This concept involves finding the antiderivative of trigonometric functions, specifically how to integrate cosine to obtain sine.
