In summary, the conversation is about finding the solution set for the equation arccos(x) - arcsin(1-x) = 90° within the interval 0° ≤ x ≤ 360°. The equation is rewritten as arccos(x) = 90° + arcsin(1-x) and the cosine of both sides is taken. Using the id...
However, when I removed the term condition of mdc.x-cos-request-id, the query was normal. I made sure that there is actually data such as mdc.x-cos-request-id equal to 84b0bb8dca944c48bb374ba01b6f3456 mapping is this { "mappings": { "_doc": { "dynamic": "runtime", "runtime...
