omg im an idiot thank you hahahaWell for starters it can’t be right as that is beyond the range for a sine function. The errors seems to be where you squared the constant term in your discriminant...

that should be rightnew solution
dividing everything by t and simplifying:
is this correct or are there specific values for theta in this range
if it is im mad rn because i did this exact same thing in the exam i just messed up the expanding and simplification cuz of algebraic mistakes. how many marks would i get?that should be right
i thought the question said there are 2 theta values you need to find not a rangenew solution

or

hm fair enough i just solved for theta values but believe had the same a similar eq at some point then everything like the u's, g's etc cancelled and i got theta =0 and some other exact valueView attachment 33789
Two times didn't give a restriction on theta
Work hard, think about concepts deeply and most of all...Hello Everyone, I am currently doing maths ext 2, will be having my HSC in 2022, any advice for me to keep in mind along the year. I do go to a school ranked in the 100s.
It will most likely take up the most time of your subjects (and should rightly so as it will comprise of 40% of your entire HSC). It is definitely rewarding with its alignment in the HSC, but that doesn't mean you should RELY on it. As said above, put in the hard work (a consistent grind), even if it is just 1/2 to an hour every day (past exams, questions, homework, etc) and let the scaling do its 'magic' for you. Youtube videos are a great source (sometimes not given enough credit by people), especially people like Eddie Woo, who explains many maths topics in such great depth and very concisely. It will be challenging, but stay perseverant and you will be able to reap the benefits from it.Hello Everyone, I am currently doing maths ext 2, will be having my HSC in 2022, any advice for me to keep in mind along the year.

DS did actually realise both of these properties which made him think the region was much more complicated than it turned out to be, so time ran out before he started on the proper graph. He has a lot of rough workings & sketches, but no idea whether they'll count for much. Overall, he thought it was a good paper which explored mathematical concepts to more depth than previous years, but he is fortunate in having the luxury of sitting next year's paper if he's not happy with his final mark.You are correct, so that means there should be open circles at and at and the boundary along the real axis between them should be dotted.
Good catch!
who is ds, are they accelerated?DS did actually realise both of these properties which made him think the region was much more complicated than it turned out to be, so time ran out before he started on the proper graph.

My ‘dear son‘ who is in Yr 11 & only accelerated in maths.who is ds, are they accelerated?
wow he must be bright if he wasn't at the least slightly perturbed by the examMy ‘dear son‘ who is in Yr 11 & only accelerated in maths.
It’s offered at certain schools depending on the child a lot of the time. You don’t “miss out” on the year 11 content you just start it a year earlier with the cohort above so in effect skipping the year 10 syllabus content.I only thought there were certain subjects you could accelerate in Year 11 (like Modern History, IPT, Business Studies, etc). I've heard of 4U students accelerating 2U in Year 11 (which obviously won't count for their HSC but can help the current Year 12 current), but never people accelerating 4U and 3U. When would they learn the Year 11 content?
