Math Trigonometric Functions

Header: #include <UnigineMathLib.h>

This class contains basic and inverse trigonometric functions.

Notice
Math trigonometrical functions are the members of the Unigine::Math namespace.

Math Class

Members


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).

float cos ( float a ) #

Returns the cosine of the given argument.

Arguments

  • float a - Argument, in radians.

Return value

Cosine of the argument.

double cos ( double a ) #

Returns the cosine of the given argument.

Arguments

  • double a - Argument, in radians.

Return value

Cosine of the argument.

float sin ( float a ) #

Returns the sine of the given argument.

Arguments

  • float a - Argument, in radians.

Return value

Sine of the argument.

double sin ( double a ) #

Returns the sine of the given argument.

Arguments

  • double a - Argument, in radians.

Return value

Sine of the argument.

float tan ( float a ) #

Returns the tangent of the given argument.

Arguments

  • float a - Argument, in radians.

Return value

Tangent of the argument.

double tan ( double a ) #

Returns the tangent of the given argument.

Arguments

  • double a - Argument, in radians.

Return value

Tangent of the argument.
