Hi People,
I'm currently doing my further science P7 GCSE OCR 21st century science But I'm stuck on the parallax trigonometry I understand trig in maths, SOHCAHTOA. However I don't understand ARC seconds and why you need to convert it into these. Can somebody help by giving an example question
-Thank you...

I think you need to be a bit more specific in your question.
Convert what?
I can tell you that seconds are just what you divide a minute into. The same as time.
A degree has 60 minutes.
So 2.5 degrees (two and a half) would be 2 degrees 30 minutes.
Half a minute would be 30 seconds.
Clearly seconds are very small angles.
Parallax angles are very small so measuring them in minutes and seconds shouldn't seem strange.
