Mastering Differentiation: The Fundamental Rule to Find the Derivative of cos(x)

๐‘‘/๐‘‘๐‘ฅ[cos ๐‘ฅ]

To find the derivative of cos(x), we can use the differentiation rules

To find the derivative of cos(x), we can use the differentiation rules.

The derivative of the cosine function is -sin(x). Therefore, the derivative of cos(x) with respect to x is -sin(x).

So, ๐‘‘/๐‘‘๐‘ฅ[cos ๐‘ฅ] = -sin(๐‘ฅ).

In summary:
The derivative of the cosine function, cos(x), with respect to x is -sin(x).
