10.5.8 TrigDegrees

Standard trigonometric functions with angles in degrees.

sinDeg( theta )

Sine of an angle.

• theta (floating point): an angle, in degrees
• return value (floating point): the sine of the argument

cosDeg( theta )

Cosine of an angle.

• theta (floating point): an angle, in degrees
• return value (floating point): the cosine of the argument

tanDeg( theta )

Tangent of an angle.

• theta (floating point): an angle, in degrees
• return value (floating point): the tangent of the argument.

asinDeg( x )

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

• x (floating point): the value whose arc sine is to be returned.
• return value (floating point): the arc sine of the argument in degrees

acosDeg( x )

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

• x (floating point): the value whose arc cosine is to be returned.
• return value (floating point): the arc cosine of the argument in degrees

atanDeg( x )

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

• x (floating point): the value whose arc tangent is to be returned.
• return value (floating point): the arc tangent of the argument in degrees

atan2Deg( y, 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.

• y (floating point): the ordinate coordinate
• x (floating point): the abscissa coordinate
• return value (floating point): the theta component in degrees of the point (r,theta) in polar coordinates that corresponds to the point (x,y) in Cartesian coordinates.
