The derivative of cos x is the negative of the sine function, that is, -sin x. Derivatives of all trigonometric functions can be calculated using the derivative of cos x and derivative of sin x. The derivative of a function characterizes the rate of change of the function at some point.

What is the derivative of cos(x)?

The derivative of cos (x) is simply -sin (x), and there are two ways to differentiate cos (x). The first method of differentiation uses Euler’s form of cos (x).

What is the derivative of the cosine function?

The derivative of the cosine function is written as (cos x)’ = -sin x, that is, the derivative of cos x is -sin x. In other words, the rate of change of cos x at a particular angle is given by -sin x. Now, the derivative of cos x can be calculated using different methods. It can be derived using the limits definition, chain rule, and quotient rule.

What is the derivative of cos x using the chain rule?

Hence the derivative of cos x has been proved using the first principle of differentiation. The chain rule for differentiation is: (f (g (x)))’ = f’ (g (x)) . g’ (x). Now, to evaluate the derivative of cos x using the chain rule, we will use certain trigonometric properties and identities such as:

What is the anti-derivative of cos x?

The anti-derivative of cos x is nothing but the integral of cos x. As the name suggests, anti-derivative is the inverse process of differentiation. The derivative of cos x is -sin x and the derivative of sin x is cos x. So, the anti-derivative of cos x is sin x + C and the anti-derivative of sin x is -cos x + C, where C is constant of integration.

As sin x is a periodic function, the graph of differentiation of cos x is also periodic and its period is 2π. A derivative is simply a measure of the rate of change. Now, we will derive the derivative of cos x by the first principle of derivatives, that is, the definition of limits.

What is the derivative of sin x cos x?

Answer: The derivative of sin (log x) is [cos (log x)] / [x ln 10]. Example 2: Find the derivative of sin x cos x using the formula of derivative of sin x. By double angle formula of sin, 2 sin x cos x = sin 2x. We know that the differentiation of sin x is cos x. Using this and using chain rule, Answer: The derivative of sin x cos x is cos 2x.

How do you find the derivative of sin x using chain rule?

Using this let us find the derivative of y = sin x (or) cos (π/2 – x) (by co-function identity ). y’ = – sin (π/2 – x) · d/dx (π/2 – x) (as the derivative of cos x is – sin x) = cos x (By one of the trigonometric formulas). Thus, we have derived the formula of derivative of sin x by chain rule.

What is the anti-derivative of sin x?

Anti-derivative means inverse process of differentiation. As we know now the derivative of sin x is cos x. Hence, the anti-derivative of sin x is – cos x + C.

Derivatives of all trigonometric functions can be calculated using the derivative of cos x and derivative of sin x. The derivative of a function characterizes the rate of change of the function at some point. The process of finding the derivative is called differentiation.

**We will use the following formulas and identities to calculate the derivative:**

- cosec x = 1/sin x
- cot x = cos x/sin x
- (sin x)’ = cos x

What are the derivatives of the basic trigonometric functions?

The basic trigonometric functions include the following 6 functions: sine (sin x), cosine (cos x), tangent (tan x), cotangent (cot x), secant (sec x), and cosecant (csc x). All these functions are continuous and differentiable in their domains. Below we make a list of derivatives for these functions.

How do you find the derivative of cotangent?

The derivative of cotangent can be found in the same way. However, this can be also done using the chain rule for differentiating a composite function: The table below summarizes the derivatives of basic trigonometric functions: In the examples below, find the derivative of the given function.

How do you find the derivative of Sine with a negative sign?

At the peaks of the cosine function (the derivative of sine) the sine function crosses the x-axis – these are the points where the sine function has the greatest slope, or is changing the most rapidly. The graphs of these trigonometric functions also give us a clue as to which derivative contains the negative sign.

How do you find the derivative of the cosine function?

Upon inspection, the graph of D ( x) appears to be very close to the graph of the cosine function. Indeed, we will show that d d x ( sin x) = cos x. If we were to follow the same steps to approximate the derivative of the cosine function, we would find that d d x ( cos x) = − sin x.
