SIN() and COS() Function in MySQL

1. SIN() Function :
SIN() function in MySQL is used to return the sine of any given number X, where X is given in radians.

Syntax :

SIN(X)

Parameter : Required.
X : A number whose sine value we want to calculate. It is given in radian.
Returns : It returns the sine of given number x.

Example-1 :
Sine of 0 using SIN() function.

SELECT SIN(0) AS Sin_Val;

Output :

Sin_Val
0

Example-2 :
Sine of 90 degree i.e 1.5707963267948966 radian using SIN() function.

SELECT SIN(1.5707963267948966) AS Sin_Val;

Output :

Sin_Val
1

Example-3 :
Sine of -90 degree i.e -1.5707963267948966 radian using SIN() function.

SELECT SIN(-1.5707963267948966) AS Sin_Val;

Output :

Sin_Val
-1

Example-4 :
Sine value of a numeric column in a table.

Table – Number

X
-1.22
-0.5
0
0.54
1.55

SELECT X, SIN(X) AS Sin_X  
FROM Number;

Output :

X	Sin_X
-1.22	-0.9390993563190676
-0.5	-0.479425538604203
0	0
0.54	0.5141359916531132
1.55	0.999783764189357

2. COS() Function :
COS() function in MySQL is used to return the cosine of any given number X, where X is given in radians.

Syntax :

COS(X)

Parameter : Required.
X : A number whose co-sine value we want to calculate. It is given in radian.
Returns : It returns the cosine of given number x.

Example-1 :
Co-Sine of 0 using COS() function.

SELECT COS(0) AS  Cos_Val;

Output :

Cos_Val
1

Example-2 :
Co-Sine of 90 degree i.e 1.5707963267948966 radian using COS() function.

SELECT COS(1.5707963267948966) AS  Cos_Val;

Output :

Cos_Val
0

Example-3 :
Co-Sine value of a numeric column in a table.

Table – Number

X
-1.22
-0.5
0
0.25
1.55

SELECT X, COS(X) AS Cos_X  
FROM Number;

Output :

X	Cos_X
-1.22	0.34364574631604705
-0.5	0.8775825618903728
0	1
0.25	0.9689124217106447
1.55	0.020794827803092428
