Finding the angle between two bearings is often confusing.<ref>[https://stackoverflow.com/questions/16180595/find-the-angle-between-two-bearings]</ref>
|
|
|
|
|
|
;Task:
|
|
Find the angle which is the result of the subtraction '''b2 - b1''', where '''b1''' and '''b2''' are the bearings.
|
|
|
|
<br>Input bearings are expressed in the range '''-180''' to '''+180''' degrees.
|
|
<br>The result is also expressed in the range '''-180''' to '''+180''' degrees.
|
|
|
|
|
|
Compute the angle for the following pairs:
|
|
* 20 degrees ('''b1''') and 45 degrees ('''b2''')
|
|
* -45 and 45
|
|
* -85 and 90
|
|
* -95 and 90
|
|
* -45 and 125
|
|
* -45 and 145
|
|
* 29.4803 and -88.6381
|
|
* -78.3251 and -159.036
|
|
|
|
|
|
;Optional extra:
|
|
Allow the input bearings to be any (finite) value.
