Apr 11, 2018 at 8:50 comment added Arnauld @OlivierGrégoire Very nice. You probably should post it as a new answer.
Apr 11, 2018 at 8:37 comment added Olivier Grégoire 65 bytes optimizing everybody's answer: (a,b,c,d,C=Math.cos)=>1737*Math.acos(C(a-c)+C(a)*C(c)*(C(d-b)-1))
Apr 11, 2018 at 8:34 comment added Kevin Cruijssen 74 bytes using @Neil's shorter algorithm: (a,b,c,d,M=Math)=>1737*M.acos(M.cos(a-c)+M.cos(a)*M.cos(c)*(M.cos(d-b)-1))
Apr 11, 2018 at 7:12 comment added Kevin Cruijssen 77 bytes using @miles' shorter algorithm: (a,b,c,d,M=Math)=>1737*M.acos(M.sin(a)*M.sin(c)+M.cos(a)*M.cos(c)*M.cos(d-b))

saved 6 bytes on the 'with' version
Apr 10, 2018 at 16:29 comment added l4m2 You can do with(Math)f=(a,b,c,d)=>3474*asin((sin((c-a)/2)**2+cos(c)*cos(a)*sin((d-b)/2)**2)**.5)
