Prototype double asin(double x);
Description Function returns the arc sine of parameter
x
; that is, the value whose sine is
x
. Input
parameter
x
must be between -1 and 1 (inclusive). The return value is in radians,
between -pi/2 and pi/2 (inclusive).
asin
Prototype double atan(double x);
Description Function computes the arc tangent of parameter
x
; that is, the value whose tangent is
x
.
The return value is in radians, between -pi/2 and pi/2 (inclusive).
atan
Prototype
double atan2(double x);
Description This is the two argument arc tangent function. It is similar to computing the arc tangent
of y/x, except that the signs of both arguments are used to determine the quadrant of
the result, and
x
is permitted to be zero. The return value is in radians, between -pi and
pi (inclusive).
atan2
Prototype
double ceil(double num);
Description Function returns value of parameter
num
rounded up to the next whole number.
