# What is the differentiation of sin x by COS X?

## What is the differentiation of sin x by COS X?

Answer: The derivative of sin x cos x is cos2x – sin2x, that is, cos 2x. Let’s understand how we arrived at the solution. Explanation: The derivative of sin x cos x can be found by using the product rule of derivatives.

What is the differential coefficient of sin x?

So the differential coefficient of f (sin x) is cot x.

### How differentiation of sin is cos?

For example, the derivative of the sine function is written sin′(a) = cos(a), meaning that the rate of change of sin(x) at a particular angle x = a is given by the cosine of that angle. Knowing these derivatives, the derivatives of the inverse trigonometric functions are found using implicit differentiation.

What is cos2x formula?

Now if you are wondering what the formula of cos2x is, let me tell you that we have 5 cos x formula. The trigonometric formula of cos2x = Cos²x – Sin²x. The trigonometric formula of cos2x = 1 – 2Sin²x. The trigonometric formula of cos2x = 2Cos²x – 1. The trigonometric formula of cos2x = 1−tan2x1+tan2x.

#### What is the meaning of differential coefficient?

Definitions of differential coefficient. the result of mathematical differentiation; the instantaneous change of one quantity relative to another; df(x)/dx. synonyms: derivative, derived function, differential, first derivative. types: curvature.

What is the integral of sin?

The integral of sinx is −cosx+C and the integral of cosx is sinx+C. …

## What is formula of Cos 2x?

Also, we know that cos (a + b) = cos a cos b – sin a sin b. We will use this to prove the identity for cos 2x. Using the angle addition formula for cosine function, we have. cos 2x = cos (x + x)

What is sin2x formula?

The sin 2x formula is the double angle identity used for sine in trigonometry. Trigonometry is a branch of mathematics where we study the relationship between the angles and sides of a right-angled triangle. There are two basic formulas for sin 2x: sin(2x) = 2 sin x cos x (in terms of sin and cos)
