d/dx cosx
To find the derivative of the function f(x) = cos(x), we can use the derivative rules
To find the derivative of the function f(x) = cos(x), we can use the derivative rules. In this case, the derivative of the cosine function is given by:
d/dx cos(x) = -sin(x)
Therefore, the derivative of cos(x) with respect to x is -sin(x). This means that the rate of change of cos(x) with respect to x at any given point x is equal to the value of -sin(x) at that point.
