Here is my small paragraph.
The accepted object is further verified by fitting a circle for a
selected slice. If the circle fitting error is lower than the
defined threshold,
it is accepted as a circular object.Can i use the article ‘the‘ with some nouns even though we are using them for the first time within a sentence?
Answer
You can use the definite article in both the cases you are talking of something very specific: the circle fitting error and the defined threshold. You are not talking of a generic error or a generic threshold.
The comma you used in that sentence is fine, and it is normally used in those cases.
If you are happy, clap your hands.
