## What is COSX integral?

∫ (1 / cos(x)) dx = ∫ sec(x) dx = ln |sec(x) + tan(x)| + C, where C is a constant. The antiderivative of 1 / cos(x) is ln |sec(x) + tan(x)| + C, where C is a constant.

## What is the antiderivative of cos x dx?

sinx

What is the antiderivative of cosx. Again, people memorize that the antiderivative of cosx is sinx.

**What is 1 divided by COSX?**

secant

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .

**What is the antiderivative of cos3x?**

The antiderivative of cos 3x is ∫cos 3x dx = (1/3) sin 3x + C, where C is the constant of integration.

### What is cos squared x?

We can derive the cos square x formula using various trigonometric formulas which consist of cos^2x. The trigonometric identities which include cos^2x are cos^2x + sin^2x = 1, cos2x = cos^2x – sin^2x and cos2x = 2cos^2x – 1. We can simplify these formulas and determine the value of cos square x.

### How do you find cos?

In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as ‘cos’.

**What is sin divided by cos?**

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .
