## d/dx[cosx]

### To find the derivative of cos(x) with respect to x, you can use the derivative formula for trigonometric functions

To find the derivative of cos(x) with respect to x, you can use the derivative formula for trigonometric functions. The derivative of cos(x) is given by:

d/dx[cos(x)] = -sin(x)

This means that the rate of change of the cosine function with respect to x is equal to the negative sine function. So, the derivative of cos(x) is equal to -sin(x).

It’s also important to note that the derivative of cos(x) is the slope of the cosine curve at any given point. The slope at any point on the cosine curve is equal to the value of the derivative at that point.
