Thread: Separation of two places

I need to find the angular separation between two points on the earth's surface. The points are as follows: 40.99N, 44.19E and 22.33N, 114.18E. I have done the maths and got 60.8 degrees. It can't be the case since 114.18-44.19 is already 69.99 degrees. Here's what I did pls tell me what's wrong. Thanks.

It can be right, two points can differ in longitude by 180 degrees and be only a few kilometres apart (so at a small angular separation)
