SINH function returns the hyperbolic sine of a value.
The hyperbolic trigonometric function takes arguments in radians where,
radians = (angle * 2 * 3.1416 / 360)
Using the SINH function to find the hyperbolic sine of 30 degrees:
SQL> SQL> SELECT SINH(30*2*3.1416/360) 2 FROM dual;-- from w w w.jav a 2 s .c o m SINH(30*2*3.1416/360) --------------------- 00000.55 SQL>
