Verified step by step guidance

Step 1: Recall the definition of an antiderivative. An antiderivative of a function f(x) is a function F(x) such that the derivative of F(x) equals f(x). In this case, we are looking for a function F(x) whose derivative is cos(x).

Step 2: Use the basic differentiation rule for trigonometric functions. The derivative of sin(x) is cos(x). Therefore, sin(x) is an antiderivative of cos(x).

Step 3: Add the constant of integration, C, to account for the family of antiderivatives. This is because the derivative of a constant is zero, and any constant added to sin(x) will still result in cos(x) when differentiated.

Step 4: Verify the result by differentiating sin(x) + C. The derivative of sin(x) is cos(x), and the derivative of C is 0. Thus, the derivative of sin(x) + C is cos(x), confirming that sin(x) + C is indeed an antiderivative of cos(x).

Step 5: Compare the given options. The correct answer is sin(x) + C, as it satisfies the condition of being an antiderivative of f(x) = cos(x).
