COSH function

COSH returns the hyperbolic cosine of a value. It takes arguments in radians where,

radians = (angle * 2 * 3.1416 / 360)

Using the COSH function to find the hyperbolic cosine of 30 degrees:


SQL>
SQL> SELECT COSH(30*2*3.1416/360) FROM dual;

COSH(30*2*3.1416/360)
---------------------
           1.14023899

SQL>
SQL>
SQL>
SQL> select COSH(3.1415926) from dual;

COSH(3.1415926)
---------------
     11.5919527
