Math Trigonometrical 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)

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

• double v - Argument.

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)

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

• double y - First argument.
• double x - Second argument.

Return value

Result in radians, which is between -PI and PI (inclusive).

Arguments

• double a - Argument, in radians.

Return value

Tangent of the argument.
