Oh wowwwwwww
Okay soooo they make the papers in school harder so in the hsc the papers are easier and then they match up the score. Also I havent even replied or typed in my thread in so longggg. I also sorta forgot to use BOS and stuff.😭😭😭😭😭
I do chemistry on monday,chem on tuesday, bio on Wednesday, nothing on Thursday, mathamatics on friday, chem on Saturday and english and bio on sunday 😀🥲🥲
"Where is Tharun and why does he keep disappearing when we need him the most"
Man I hate this…hopefully i can still drop my subject that i want GONE FOREVER
bio was never the easiest science it is just people spreading this rumour lol
I am goanna hate staying back on Wednesday for Vet fitness I will forever regret taking this subject as its non atar and eats up all my time.Ontop of that I will probably have to wait until week 8 before fully dropping.I wish I had a time machine to repick all my subjects.😭

guys when ur doing trig functions is it necessary to know how to do it without subbing in values into the calculator. For me it's faster that way but my teacher doesn't want us to do that cause we're in "adv". I'm actually not bothered tho cause the other way is so much longer

I don't think its necessary to know how to do it without subbing in the values to the calculator. I do that too. Idk how my friend just remembers the outcome of sinθ, cosθ, tanθ at different θ values just by practicing questions, unless I was intentionally trying to remember them.

it's definitely useful to be able to know the values/the general shape of the common trig functions because it can also be useful in reverse
(like if you need to find the value of theta for which sin(theta) = 1/2)
it's still fine if you sub tho

but isn't inverse only for ext?

yeah screw my teacher I am gonna learn it for the sake of my teacher not harassing me every lesson but in the exam I am def subbing in values into my calculator. She just hates it when we memorise stuff and she wants us to "understand" cause that's how she found the "beauty" of math. But I just want to get it done the easy way bruh

wym they're pretty easy just gotta know the unit circle and values of each function for 0, 30, 45, 60 and 90 degrees for each function. if u memorise it (not that hard to memorise the same numbers over and over again) u'll be doing integration n stuff quicker. but obviously for like angles like 56 degrees or whatnot, you need a calc for it

no but like graphing them. Like for example cos (x- pi). They're easy but I'm just not bothered

tbh i just think everybody has a different approach. if it works, it works. all that matters is that you get the graph drawn, right? 🤷‍♀️
although there are questions that are like "in order to get from a certain trig graph to another trig graph, how would you do it?" so i think being comfortable w trig translations would be quicker than a table of values in that case. but that isnt a very common question so i suppose you don't need to worry ab it anyways
