This Oracle tutorial explains how to use the Oracle/PLSQL TAN function.
The Oracle/PLSQL TAN function returns the tangent of n.
TAN
returns the tangent of a value.
The TAN
function take arguments in radians where:
radians = (angle * 2 * 3.1416 / 360)
The syntax for the Oracle/PLSQL TAN function is:
TAN( n )
n is a number. It is an angle expressed in radians.
select TAN(3.1415) from dual;
Using TAN
function to find the tangent of 30 degrees:
SQL> select TAN(30*2*3.1415926/360) From dual;
TAN(30*2*3.1415926/360)
