Because the sign only remains constant, when taking the derivative of sine. The sign flips every time you take a derivative of cosine. Sine's derivative follows a certain cycle. Start with +sine. 1st derivative: +cosine 2nd derivative: -sine 3rd derivative: -cosine 4th derivative: +sine. Back where we started.
