### What is the use of COS function?

Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse. The cosine function is one of the three main primary trigonometric functions and it is itself the complement of sine(co+sine).

**What is the use of COS function in VB?**

The Cos function takes an angle and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse. The result lies in the range -1 to 1. To convert degrees to radians, multiply degrees by pi/180.

## What is cos a cos B?

Cos A + Cos B is an identity or trigonometric formula, used in representing the sum of cosine of angles A and B, Cos A + Cos B in the product form using the compound angles (A + B) and (A – B). Here, A and B are angles.

**How to calculate cos (x) series using X and N?**

We are given with the value of x and n where, x is the angle for cos and n is the number of terms in the cos (x) series. Cos (x) is a trigonometric function which is used to calculate the value of x angle. Cos (x) = 1 – (x*2 / 2!) + (x*4 / 4!) – (x*6 / 6!) + (x*8 / 8!)…… Input the value of x and n Apply the formula for calculating cos (x) series

**How do you program a cosine series in C?**

Program code for Cosine Series in C: Working: First the computer reads the value of ‘x’ and ‘n’ from the user. Then ‘x’ is converted to radian value. Then using for loop the value of Cos(x) is calculate. Finally the value of Cos(x) is printed.

### How do you find the sum of the cosine series?

Program for sum of cos(x) series. Given n and b, where n is the number of terms in the series and b is the value of the angle in degree. Program to calculate the sum of cosine series of x and compare the value with the library function’s output. Formula Used : cos x = 1 – (x 2 / 2 !) + (x 4 / 4 !) – (x 6 / 6 !) +….
