Hello
Does it make sense to write:
"The formula definition of these indicators is recalled in the annex"/
Context :
it is about mathematic definitions of the indicators
Thanks
"these indicators" makes it plural so use "are"
"The formula definition of these indicators
are described in Annex A.
"The formula definition of these indicators
are listed in Annex A.
"The formula definition of these indicators
are shown in Annex A.
"The formula definition of these indicators
are given in Annex A.
Or any other word which describes what your Annex contains
and how it is laid out.
When referring to Appendices and Annexures you would write (note the capitals):
...in Annex A.
or
...in Appendix 1 to Annex A.
All Annexures are lettered - even if there is only 1 (A, B, C,... AA, AB, etc.).
All Appendices are given a number - even if there is only 1. (Appx 1, 2, 3, etc. to Annex A, Appx 1, 2, 3, etc. to Annex B, etc.)
