Step 1: Understand that we want to find the integral of sin x with respect to x.
Step 2: Recall the basic rule of integration for sine functions: the integral of sin x is -cos x.
Step 3: Add the constant of integration, C, because the integral can have many values depending on the constant.
Step 4: 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.
