Wish I discovered this channel earlier

I just did it for fun and got the same answer, my brain isn't complete mush yet. The trick for the last one is not to find t (but I don't think you could anyway as lots of values would work) but to find cos t and cos 2t as that's part of the parametrization.

where can we watch the live recording from wednesday?

PLEASE NEVER STOP W THIS SERIES. MAYBE DO ONE FOR FM TOO PLS

Hi Mr Asterbury would it be possible to make a video of #3d trigonometry from series 2 for IGCSE? I understand if it's not possible and appricate all the work you have given to everyone for free!

First (please say "bosh!")

BOSHHHHH!!!

sir I did this funnily i solved the Cartesian equation then subbed it in to l i got the same answer but is your version faster

Hello, sir I would like to suggest you do more IGCSE questions as the exam is very close.

To find the y value for the last question I tried to draw a mini triangle with the adjacent side as 5, hypotenuse as 6 and opposite as root11. That then gives me sint=root11/6 and we already know cost so then I did y = 2root3sintcost but that gives me an answer of 5root33/18. Is the method valid and I just made a mistake or the method not valid?

Unrelated question but are the mock edexcel papers generally harder than past papers ?

Hi sir, I did this question and ended up getting the exact (correct answer) for part C but i did it a completely different way, would i still get the full marks?

I wasted a solid extra minute on (b) and sort of blindly powered through with doubt, all because I bloody rationalised the denominator when finding -dx/dy, which meant I did much more unnecessary manipulation to get the equation in the form they wanted.. curse whoever decided that curriculum should emphasize 'rationalising the denominator', so superfluous lol

no way i literally just did the sample paper that contains this question like an hour ago 😂 it was easy tho

These are from the mock set papers right?

@@MrAstburyMaths oh right, I got confused because I done this paper today along with mock set papers

Last please say bosshhhh

is this edexcel, feels like it’s way too easy for 13 marks

It’s easy until the grade boundaries screw everyone over because the test wasn’t hard enough (rip my 2023 AQA fallen soldiers)

you'd be surprised how many people get those questions wrong, probably less than 30% of people got that entire question right.
