This function gives you a way to specify a degree angle while in
Gradian or Radian mode.
In Radian angle mode, multiplies the argument by p/180.
In Degree angle mode, returns the argument unchanged.
In Gradian angle mode, multiplies the argument by 10/9.
Note: You can insert this symbol from the computer keyboard by
typing @d.
In Degree, Gradian or Radian angle mode:
In Radian angle mode:
¡
, ', '' (degree/minute/second)
/k keys
dd¡mm'ss.ss'' ⇒ expression
dd A positive or negative number
mm A non-negative number
ss.ss A non-negative number
Returns dd+(mm/60)+(ss.ss/3600).
This base-60 entry format lets you:
• Enter an angle in degrees/minutes/seconds without regard to the
current angle mode.
• Enter time as hours/minutes/seconds.
Note: Follow ss.ss with two apostrophes (''), not a quote symbol (").
In Degree angle mode:
±

[Radius,±q_Angle] ⇒ vector
(polar input)
[Radius,±q_Angle,Z_Coordinate] ⇒ vector
(cylindrical input)
[Radius,±q_Angle,±q_Angle] ⇒ vector
(spherical input)
Returns coordinates as a vector depending on the Vector Format
mode setting: rectangular, cylindrical, or spherical.
Note: You can insert this symbol from the computer keyboard by
typing @<.
In Radian mode and vector format set to:
rectangular
cylindrical
spherical
(Magnitude ± Angle) ⇒ complexValue
(polar input)
Enters a complex value in (r±q) polar form. The Angle is interpreted
according to the current Angle mode setting.
In Radian angle mode and Rectangular complex format:
