Mathematical Functions
FUNCTION
sin finds sin
HEADER
math.h
FUNCTION PROTOTYPE
double sin (double x);
Function
sin
Arguments
x ... Numeric value to perform
operation
Return Value
Normal ... sin of x
When x = NaN, x = 屉 ... NaN
When underflow occurs ...
Non-normalized number
EXPLANATION
⢠Calculates sin of x.
⢠If x is non-numeric, NaN is returned.
⢠If x is infinite, NaN is returned and EDOM is set to errno.
⢠If an underflow occurs as a result of the operation, a non-normalized number is returned.
⢠If the absolute value of x is extremely large, the result of an operation becomes an almost meaningless value.
