Creates an angle in the metric of radians, degrees, and turns.
Usage
ob_angle(.data = class_missing)
degree(degree = class_missing)
radian(radian = class_missing)
turn(turn = class_missing)Details
Angles turns can be any real number, but degrees are displayed as values between -360 and +360, and radians are between -2pi and +2pi.
Examples
# Three Different ways to make a right angle
## 90 degrees
degree(90)
#> 90°
## half pi radians
radian(.5 * pi)
#> 0.5π
## A quarter turn
turn(.25)
#> .25
# Operations
degree(30) + degree(20)
#> 50°
degree(350) + degree(20)
#> 10°
degree(30) - degree(30)
#> 0°
degree(30) - degree(50)
#> −20°
degree(30) * 2
#> 60°
degree(30) / 3
#> 10°
radian(1) + 1 # added or subtracted numbers are radians
#> 0.64π
degree(10) + 10 # added or subtracted numbers are degrees
#> 20°
turn(.25) + .25 # added or subtracted numbers are turns
#> .50
# Trigonometric functions work as normal
sin(degree(30))
#> [1] 0.5
cos(degree(30))
#> [1] 0.8660254
tan(degree(30))
#> [1] 0.5773503
