I can't solve Question 5. (d) (ii) 2005 HSC Paper although i have the correct method because it overloaded my casio calculator, fx-100AU (too many digits).
I'm aware of how stupid this sounds but I need help.
Question 9. (b) of HSC 2003 paper.
I noticed to find the angle to solve (iii) you need to use the double-angle rule (in a circle the angle at the center is double of the angle at the circumference, when the angles have the same circumference as base) which I faintly remembered back from year...
