SUMMARY
The derivative of -sin(x) is definitively cos(x). This conclusion is based on the rule that the derivative of sin(x) is cos(x), and since -1 is a constant multiplier, it can be factored out during differentiation. Therefore, the derivative can be expressed as d/dx((-1)(sin(x))) = (-1)(cos(x)). Understanding this concept relies on the linearity of differentiation.
