Math Trigonometric Functions
float acos ( float v ) #
Returns the arc cosine of the given argument - the angle in radians, whose cosine is equal to the argument. a == cos(acos(a)) for every value of a that is within acos()'s range.Arguments
- float v - Argument.
Return value
Arc cosine of the argument, in radians.double acos ( double v ) #
Returns the arc cosine of the given argument - the angle in radians, whose cosine is equal to the argument. a == cos(acos(a)) for every value of a that is within acos()'s range.Arguments
- double v - Argument.
Return value
Arc cosine of the argument, in radians.float asin ( float v ) #
Returns the arc sine of the given argument - the angle in radians, whose sine is equal to the argument. a == sin(asin(a)) for every value of a that is within asin()'s range.Arguments
- float v - Argument.
Return value
Arc sine of the argument, in radians.double asin ( double v ) #
Returns the arc sine of the given argument - the angle in radians, whose sine is equal to the argument. a == sin(asin(a)) for every value of a that is within asin()'s range.Arguments
- double v - Argument.
Return value
Arc sine of the argument, in radians.float atan ( float v ) #
Returns the arc tangent of the given argument - the angle in radians, whose tangent is equal to the argument. a == tan(atan(a)) for every value of a that is within atan()'s range.Arguments
- float v - Argument.
Return value
Arc tangent of the argument, in radians.double atan ( double v ) #

Return value
Arc tangent of the argument, in radians.float atan2 ( float y, float x ) #
Returns the arc tangent of two arguments (x and y). It is similar to calculating the arc tangent of y / x, except that the signs of both arguments are used to determine the quadrant of the result.Arguments
- float y - First argument.
- float x - Second argument.
Return value
Result in radians, which is between -PI and PI (inclusive).double atan2 ( double y, double x ) #
