Exam Hack | CIE A2 Maths | P3 | Trig Identity Question

Hi, a bit update, I tried using on my chrome but it says the address has temporarily or permanently moved🥲

Daania Amelia

Sorry for the late response, but what if I'm currently using the app? What do you reckon I should do?

Daania Amelia

It might be a browser problem or if your "privacy" settings are too strong. Chrome / Chromium based browsers work

Hi I just recently joined, I'm wondering why can I download the worksheet but the video doesn't play, it has this white screen But some other chapters have videos that can be played but mostly other chapters have white screens🙏

dropped a fat like

I am only sad that this will mean I no longer get to watch your videos. No more shitty drawings ( they were better than mine) no more jokes no more philosophy ( after physics) no more listening to the same "music for studying / focus". Love ya intuitive and thank you. May I one day end up being as curious about the world as you are. :))

THANK YOU SO MUCH! before the exam today I knew i had to go in there and make you proud!!! and i really think I did!! everyone was complaning about how hard the exam was and honestly if it werent for you I wouldve probably done the same. MR INTUITITVE THANK YOU SO MUCH YOU MADE ME SO MUCH BETTER AT P3. I LOVE UUU

Wasi Hussain

Thanks a lot man you really saved me. I've been following your videos both for AS and A level for about a year now and you managed to basically teach me everything from scratch. I just had my p3 exam today and AS exams earlier and they all went better than I could have imagined. Thank you so much, me and my friends won't forget you <3

Thank you so much! Had 9709 P33 this morning and it went phenomenally well! Wouldn't have been possible without you Jacob. Very grateful that you provided this content at such a low cost. I need an A in Maths to fulfil my LSE offer and I'm very confident that I'll get it now.

Good luck to you too

You got this don't stress it , I'm writing the exam in 2 hours so I'm doing some last minute revision also. Goodluck <3

"the most intuitive one, the one that makes sense" kinda felt like when they say the name of the movie in the movie 😭😭

nope

can I use the Fx-CG50 calculator in my Alevel maths exam?

Andrew the physicist

you can change the output settings so it shows the exact answer. it will probably be shift + setup or something like that, but it depends on what calculator model you have. so you can google your calculator's name and how to change its settings. hope that works

Why in my calculator it is 2.64575 but not square root of 7, I know it is the same but why?

晓 汤

Hi! I’m running into the same problem with my calculator where it’s not showing sqrt(7) in its exact form. Do we just need to use Pythagorus thereom in this case? Thanks!

Aida

On your formulae sheet. Also you can prove it : tan^2(x) = sin^2(x)/cos^2(x) = (1-cos^2(x))/cos^2(x) = [1/cos^2(x)] - [cos^2(x)/cos^2] = sec^2(x) - 1

Intuitive

why not substitute tan^2 with (sec^2 -1) ?

Tahsan

Where can we download the worksheet please?

Bro they ar the same thing it gives the same answer just add it on your calculator you would get the same answer

Hello. Just wanted to ask about the 3rd question u solved in this video . In the 3cos(x-45) . After we used the formula for the formula sheet . We got cos x cos 45 +sin x sin 45 .. in ur video u did cos 45 = 1/√2 .... But here on my calculator it says √2/2 . Pls check and tell me If I am mistaken or the problem is from ur calculator . And thank alot for the video

Rramb

Thank you!! Honestly took me a while to get through this video cos I try to complete the question you do and these questions are always difficult for me but I got there in the end. Just gotta have a go at the worksheet now

Georgia

Oh, sorry. I see what happened now. Thank you

Ntokozo K.

No I just changed it I multiplied the fraction by (2/2). Hence, (3/sqrt(2))*(2/2) = 6/2*sqrt(2)

Intuitive

Ntokozo K.

Ok thank you

Aditya Gupta

Well plug it into your calculate and you will get a value. If that value is the same as what I got then you are correct.

Intuitive

Is it acceptable?

Aditya Gupta

Hi sir for the angle sum first question (i) my final answer is tanx = (sqrt(3) + 3sqrt(2)) /( 1-3sqrt/(2) )

Aditya Gupta

Thank you brother. Glad the videos are useful to you :)

YOU ARE AN ABSOLUTE LIFE SAVER MAN!! i'm so glad i supported you patreon!

Hey, have you done iterations

Tuntu Mwakalasya

Your videos help me out so much Thank you !!!!

Connie Kimani

But I guess if you wanted to do it mathematically. Then just set up a triangle from the equations to get R = sqrt(7). I'll do it on paper and send you a picture on instagram. :)

Intuitive

Yes mine doesn't either. I just knew it of by heart, I've seen so many of these questions I know what these exact values are in decimal form. Sqrt(7), Sqrt(3)/2, 1/sqrt(2)...etc. They are pretty common.

Intuitive

Hello. I am working through Q5(i) of the R and Alpha -Typ 3, I understand everything and get the correct answers however I run into a problem when trying to get the 'exact value' of R. I am dividing 1 by sin(22.208) and I get 2.646 as the answer which is the square root of 7 but not the correct answer ofc. When you did it in the video, you seemed to do it really quickly. Does your calculator give you the answer as a surd? I am using a regular Casio calculator. If my calculator can't give it to me as an exact value is there another way that I can turn my answer into the right form?

Jessica Zziwa

Amazing so happy for him! Stay tuned for my P3 content on here. Hope you're well Luisana :)

Intuitive

Hi Jacob!!! THANK YOU, this is definitely a resource I'll be using!!! By the way, I wanted to tell you that Tony got an A !!!!!!!!!!!!!!!!!!!!!!!!!!!! In Statistics 1 (also in Pure 3)!!!! So THANK YOU!!! In case you don't know, we didn't even open the Statistics' book. We solved YOUR WORKSHEETS!!!!!!!!!!
