Differentiation of cos 2x

The derivative of cos square x is equal to the negative of the trigonometric function sin2x.

Derivative of cos 2x is -2 sin 2x which is the process of differentiation of the trigonometric function cos 2x w. It gives the rate of change in cos 2x with respect to angle x. The derivative of cos 2x can be derived using different methods. In this article, we will prove the derivative of cos 2x using different methods including the first principle of differentiation and chain rule. We will also compare the graphs of the trigonometric function cos 2x and the derivative of cos 2x along with some examples. The derivative of cos 2x is negative of twice the trigonometric function sin 2x, that is, -2 sin 2x. To derive the derivative of cos 2x, different trigonometric formulas and identities are used along with some rules of differentiation.

Differentiation of cos 2x

Note that in this post we will be looking at differentiating cos 2 x which is not the same as differentiating cos 2x. Here is our post dealing with how to differentiate cos 2x. The first method is by using the product rule for derivatives since cos 2 x can be written as cos x. The product rule for differentiation states that the derivative of f x. The Product Rule: For two differentiable functions f x and g x. The chain rule is useful for finding the derivative of a function which could have been differentiated had it been in x, but it is in the form of another expression which could also be differentiated if it stood on its own. Although the expression cos 2 x contains no parenthesis, we can still view it as a composite function a function of a function. Now the function is in the form of x 2 , except it does not have x as the base, instead it has another function of x cos x as the base. The Chain Rule: For two differentiable functions f x and g x. Just be aware that not all of the forms below are mathematically correct. We can then apply the chain rule to find F' x. View all posts by DerivativeIt. The second method is by using the chain rule for differentiation. We can write cos 2 x as cos x 2.

Differentiation of cos 2x

Learn what is the derivative of cos 2x and understand how to prove the derivative of cos 2x by first principle, chain rule and quotient rule. Derivatives have a wide range of applications in almost every field of engineering and science. The derivative of cos 2x can be calculated by following the rules of differentiation. Or, we can directly find the derivative of cos 2x by applying the first principle of differentiation. The derivative of cos 2x with respect to x is -2sin 2x, which tells us how fast the cosine function is changing. In a triangle, the cosine function represents the ratio of the length of the adjacent side to the length of the hypotenuse. By knowing the rate of change of the cosine function, we can analyze the behavior of various systems and make informed decisions. Also we can find the derivative of cos 3x just by replacing 2 with 3 in the derivative of cos 2x.
