Calculate sines and hyperbolic sines.
double sin(
double x
);
float sin(
float x
); // C++ only
long double sin(
long double x
); // C++ only
float sinf(
float x
);
double sinh(
double x
);
float sinh(
float x
); // C++ only
long double sinh(
long double x
); // C++ only
float sinhf(
float x
);
Parameters
- x
Angle in radians.
Return Value
sin returns the sine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result occurs
sinh returns the hyperbolic sine of x. If the result is too large, sinh sets errno to ERANGE and returns ±HUGE_VAL, by default.

See _doserrno, errno, _sys_errlist, and _sys_nerr for more information on these, and other, return codes.
Remarks
C++ allows overloading, so users can call overloads of sin and sinh that take double, float or long double types. In a C program, the sin and sinh functions always take and return double and float, respectively.
