WebThe graphs of these trigonometric functions also give us a clue as to which derivative contains the negative sign. At x = 0, sin(x) is increasing, and cos(x) is positive, so it makes sense that the derivative is +cos(x). On the other hand, just after x = 0, cos(x) is decreasing, and sin(x) is positive, so the derivative must be −sin(x).
