## Derivative of Sin

### The derivative of the function sin(x) with respect to x can be found using the basic differentiation rules

The derivative of the function sin(x) with respect to x can be found using the basic differentiation rules.

The derivative of sin(x) is equal to the cosine of x. This can be written as:

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

To understand this, we need to recall the definition of the sine function and how it changes with respect to x.

The sine function, sin(x), represents the ratio between the length of the side opposite to an angle in a right triangle and the length of the hypotenuse. It oscillates between -1 and 1 as the angle varies.

The derivative of a function represents the rate at which the function is changing at a given point. In the case of the sine function, the derivative tells us how fast the values of sin(x) are changing as x changes.

The cosine function, cos(x), represents the ratio between the length of the side adjacent to an angle in a right triangle and the length of the hypotenuse. It is also oscillates between -1 and 1 as the angle varies.

Since the sine and cosine functions are closely related, their derivatives are also related. Specifically, the derivative of sin(x) is equal to cos(x).

So, when we take the derivative of sin(x) with respect to x, we get cos(x), which gives us the rate at which the values of sin(x) are changing at any given point.
