had to revisit this video because i forgot everyting i studied about trignometry, mostly relating to solving questions. feeling much more confident now
Glad it helped Hoel! 🙂
I needed this badly
Glad I could help out! :-)
Always very interested to learn something like this ❤
Glad you enjoyed it! :-)
Great video sir I was actually watching your 10k subscriber special earlier today it brought back some memories! You’re about to blast 30k incredible sir! I miss your videos sir! Keep it up! Sorry I’ve not posted I’ve posted more on TikTok this year
Wow, you've been doing some serious RUclips time travel! Thanks for watching the 10k subscriber special, and don't worry, I'll try to keep up with your expectations as I blast past 30k! :-)
U don't know how much this means to I have my math end of term after tomorrow and trig will be a big part of it
Thank you so much for sharing! It means a lot to know that my video is helping you prepare for your math exam. Good luck!
hi sir i have a question, when it comes to using the calculator, how do i know when it should be in radians or degrees..
When the domain is written in terms of pi or not...
Hey ginger could you please make a detailed lesson series on the complete ibdp maths ai course. That covers the complete new syllabus
Probably won't have time soon but like to make this a long term project at some point :-)
Sort of an irrelevant comment, but the german fact about the quadratic formula was fun to know because other than a-levels, German is what I'm learning as well (also for a-level)! Which is a rather uncommon crossover, so it was rather pleasant and interesting! Thank you for the informative video, haben Sie einen tollen Tag!
Gleichfalls 🙂 I will teach occassionally in German at the moment so es bleibt im Kopf sozusagen 😉
5:18 here could you just say let x = cos theta and then use the formula from there?
Exactly 👍
thankyou sir
sir what about the sectheta cosec theta and cot theta
Not on P1 :-)
Could you please send link to the presentation
36:26 Does the M1 mark mean we can say u =cos^2 x and solve?
It does 👍
can i pleas have the presentation/document link so that i can print and practice
Method 1)
(- x= 6) equation is given
Multiplying both sides by (-1)
-1*-x=-1*6
Then x=-6
or
Method 2)
Let the equation be (- x= 6)
If we multiply both sides with "MINUS" sign -(- x)= -(6)
Then x= -6.
Which one method is correct or both method are correct.
Please help
Both methods are completely valid!
14:05 why did you mutliply it by cosθ/cosθ ??
To get a common denominator of cos theta for both fractions 😊👍
so glad all of A level P1 is finished☺ looking forward to p5
Working on it 😊
In the question 11a rather than the part where you factorise and manually calculate the values for 4cos^2 x-3 and cos^2x +1, shall i not just use the function from the calculator to solve quadratic equations and get the values and move ahead? or is it compulsory to solve it manually?
By the way your explanations are really helpful! thank you sooo much!
sir lets say we have a question... 5tanx^2 = 5tanx.....why cant we just divide the whole thing by tanx. because i seem to be losing solutions when i do that. would you know the correct method?
You would need to factorise it like a quadratic and solve so you would not lose solutions :-)
THANK YOU SO MUCH SIR !! this definitely was much needed. you are the best
Great to hear 🙂👍
and at 39:33 why can't you use 1.5 for cos theta? why does it have to be -1>theta>1? just to brush up on concepts i'm not clear on...
The range of cosine is between -1 and 1, so 1.5 is not a valid answer :-)
need a little help at 10:25 im confused i thought we had to add 51.827…to 270 rather than minus from 360. why is that?
It is because of the symmetry of the graph. Think of it as a mirror at theta = 180 degrees.
hi sir at 31:07-32:07 how did you get the negative solutions using π? Why do you + and - π/6 from π?
Because we have both Root(3) / 2 and - Root (3) / 2 to consider, so there should be 4 answers in total :-)
Thank u so much I have mocks in 3 weeks and I was struggling with it may god bless u❤
No problem Masoud 👍
Hello, I appreciate all the hard work that you invest in every video!!! Just wanted to ask - how do you know when to substitute something with an identity? Ffor instance, 12:33 step 1 is tan(x) is immediately substituted with identity, whereas 16:27 step 1 sin^2(x) is not substituted immediately (hope the question makes sense lol)
Depends on the question, I am trying to make it look like the right hand side so I perform substitutions to get closer to the form required :-)
@@GingerMathematician Got it, thank you!
I really need explanation for p3 topics pleaseeee
Won't have time at the moment sorry 😕
pleaseeeeeeeeeeeeeeeeeeeeeeeeeeee@@GingerMathematician
bro is the absolute legend i love you so much i think i'll go from U's to A's
Love the positivity! My A-Level Maths P1 videos are now complete 🙂👍
YOU ARE A HERO! Thank you so much 🥰
No problem 😊
At this moment, you are my most trustable maths tutor
i think i got this
Gone through the whole playlist? 😊 ruclips.net/p/PLYNwTLhq9xZbPekX7M6tinBY3XqDf22UB&si=0ivqj_scuUXxGI3z
