Yes as thats kinda what an inverse function is. Eg: cos^-1x=y. You can take the cos on both sides and you get x=cos y which is the same as reflecting it in the y=x line. Edit: I'm an idiot not the same thing.
A GOOD EXAMPLE OF TEACHER CENTER: I admired him as a good lecturer!!! This teacher is very very knowledgeable but i wonder if he is teaching in high school students or college students. it seems like he is just lecturing. he does not get any feedback from students. he asked questions and he answered himself basically like a TV show, not really having students engaged in the discovery. This is the old fashion teaching, ( teacher center ) . I m also a math teacher in the states, and i will kill my class by just lecturing. i rather asked my students watch some youtube classes online at home then do activities( hands-on) in class. what he is doing is throwing stuff at his passive students, and i don't see what they students are doing ( probably sleeping). This teacher with all due respect, it is all about him, not about the students. I would like to see a teaching process more like student center, not teacher center.
I don't know. Honestly he's helping a lot by his videos. Usually the teachers from Brasil only tell us to try to solve some problem but barely explain it's origin so I ends up by decoration of formulas. Yet he hasn't filmed the whole class, so maybe he asked students to search for it and try to resolve the equations and then he filmed himself explaining the subject. In any way, if it's helping me and other people I don't see any problem.
He teaches high school. He does engage with the students but back during this video, he used to teach at James ruse, which is ranked 1st in Australia, so most of the students have already done the content and he’s giving them revisions
At this time he taught at Jame Ruse Agricultural High School. If you look it up, you'll find that it is in fact the best high school in Australia. Additionally, judging by when this video was published (Oct), it is just before the final high school exams in Australia. Thus, it is highly possible that this was just a revision lesson for his class before their final exams.
This is when he first began. At this time he'd only been teaching a couple years. I sorta agree with you. However teaching is a skill that, if you watch newer videos, he masters.

9 years later, this guy still looks the same with a cooler haircut 😂
Can we flip the cosine graph about x=y line , like we did for sin^-1(x)
Yes as thats kinda what an inverse function is. Eg: cos^-1x=y. You can take the cos on both sides and you get x=cos y which is the same as reflecting it in the y=x line. Edit: I'm an idiot not the same thing.

can you also cover some 4u topics?

graph of relation sin inv relation was wrong
yes.
sin curve should be below the line y=x where x0.
and vice versa for sin inverse
That is because his line y=x is wrong. That is where the error is coming from.
