Finding distance between 2 geospatial location in aws neptune with opencypher query language

I am working with amazon neptune and using openCypher query language and doing some stuff using notebook. I have latitude and longitude of 2 points and I want to calculate the distance between these 2 points. For the purpose I am using Haversine formula. However to do this it required trigonometric functions like sin and cos and seems that those are not supported yet with neptune and openCypher. I am stuck here as I will be heavily doing operations on location. Any alternate solution without using sin cos ?
