Sin(), Cos() and Tan() Function in MariaDB

1. Sin() Function :
In MariaDB, SIN() function is used to returns the sine of a number. In this function, a number will be passed as a parameter and this function will return the sine of that number. The number used to calculate the sine. It is expressed in radians.

Syntax :

SIN(number)

Parameter : Required. A numeral value.

• number – A number that is used for sine.

Returns : Sine of a number in radians.

Example-1 :

SELECT SIN(0);

Output –

0

Example-2 :

SELECT SIN(3.5);

Output –

-0.35078322768961984

Example-3 :

SELECT SIN(-7);

Output –
