Class TrigDegrees

Method Details

• sinDeg

  public static double sinDeg(double theta)

  Sine of an angle.

  Parameters:

  theta - an angle, in degrees

  Returns:

  the sine of the argument

• cosDeg

  public static double cosDeg(double theta)

  Cosine of an angle.

  Parameters:

  theta - an angle, in degrees

  Returns:

  the cosine of the argument

• tanDeg

  public static double tanDeg(double theta)

  Tangent of an angle.

  Parameters:

  theta - an angle, in degrees

  Returns:

  the tangent of the argument.

• asinDeg

  public static double asinDeg(double x)

  Arc sine. The result is in the range of -90 through 90.

  Parameters:

  x - the value whose arc sine is to be returned.

  Returns:

  the arc sine of the argument in degrees

• acosDeg

  public static double acosDeg(double x)

  Arc cosine. The result is in the range of 0.0 through 180.

  Parameters:

  x - the value whose arc cosine is to be returned.

  Returns:

  the arc cosine of the argument in degrees

• atanDeg

  public static double atanDeg(double x)

  Arc tangent. The result is in the range of -90 through 90.

  Parameters:

  x - the value whose arc tangent is to be returned.

  Returns:

  the arc tangent of the argument in degrees

• atan2Deg

  public static double atan2Deg(double y, double x)

  Converts rectangular coordinates (x,y) to polar (r,theta). This method computes the phase theta by computing an arc tangent of y/x in the range of -180 to 180.

  Parameters:

  y - the ordinate coordinate

  x - the abscissa coordinate

  Returns:

  the theta component in degrees of the point (r,theta) in polar coordinates that corresponds to the point (x,y) in Cartesian coordinates.
