ive had enough

I used his videos so much for my GCSEs and I am confident in saying he is one of the reasons to how I got an 8. I didn't he made A level videos and I have been struggling without his help till now. I am doing far better now thanks to you

I don't understand how these videos are not more popular! You are doing a true service for the good maths education with these videos. (Particularly A-Level, these are much better than the competition).

Thanks my g, really helped with my A Level maths

12:09 you could also remove the 5 common from 5sin2theta + 5cos2theta to get 5(sin2theta+cos2theta) which is equivalent to 5

You got me a A 89% at IGCSE math 💓💓

Thanks a lot man 🙏. I tried to learn this so many times and couldn't understand it but now you taught me the method my a level maths teachers could never teach. If it wasn't for you, I would be failing a level maths. God bless you

Thank you so much! Just one thing though: Have you considered using a thinner pen/marker for your whiteboard? I think it would just make your videos all the more perfect!🥰

bro can you please make a playlist on AS topics for stats and mechanics? It would be extremely helpful

I passed my IGCSE math with an A coz of this guys. Teachers were just waffling. Now I'm back for A level and he still the reason. I LOVE YOU MR TUTOR!!!!!!!!!

Why couldn’t you just factorise the 5sin^2 +5cos^2 >>> 5(sin^2+cos^2) >>>> 5(1) >>> 5, am I correct or?

extremely helpful, thank you so much

These videos are genuinely a life saver, thanks.

I love this guy I swear 😭😭😭

Thanks for this amazing video Sir! Is there any chance possible if you may go through the quadrant method used to solve trigonometric functions as that is another method used for solving trigonometric functions and equations sir. Thanks for producing these amazing helpful and straight to the point chapter videos 👍👍👍🔥🔥🔥

Dear Sir At 4:19 minutes, on the graph of exact trig values you wrote that cos45 and sin45 equal to 1 over root 2. They're both actually equal to root 2 over 2 Sir. Thank you very much more, I'm understanding the concepts coz of this vid!😊

Oh my god this helped so much. Thank you thank you thank you. Really appreciate your work and channel.

Hey sir, can you do AS stats and mechanics as well?

video helped so much. I'm watching this in preparation for my further maths mock exaam and this has saved me.

are you going to do the statistics and mechanics?

well done, thank you sir

You are incredible

In the solving trig equations chapter, using the quadratic method wouldn't you only get the first two answers? Because 57 and 122 fall into the A and S quadrants, and the other two values fall into the T and C quadrants?

Lovely video! I finally understood this topic thanks to you sir.

You are my life saver🎉

this is really helpful thank you so much

I don,t understand the example where where we show the equation equals to 4-5 cos0. You changed the sign for the quadratics and when you found your 2 answers, you also changed the (5x-4) into (4-5x). The sign (-) follows the 4 not the 5 but you just swapped it. Can you please explain this part? I don’t understand it at all.

this was so useful, thank you!

Many thanks for breaking this down slowly and step by step

25:55 i did not understand why you changed one of the minus signs to plus. isnt it supposed to stay minus?

Hello sir at around 27:14 how can (5x-4) be written as (4-5x), do you rearrange to first get (-4+5x) and then multiply that by (-1) to get (4-5x)

Can I ask ...in the first example can we just factor out 5 Then turn everything into 1?

27:21 why wouldn't it be (3+2x)(-4+5x) because you need negative 12, so why would the 4 be positive??

Sir please do more Alevel vidoes these are saving me !!! u lift soo much stress off my head

well i finally learnt how to factorise properly in this video ❤

Is there any possibility that you would go through A2 pure maths before our exam 2022?

banga vid like usual chap

Thank you so much for this! The textbook uses the circle method but my teachers use this method - much simpler imo

At 11:00, could u not have factorised the 5 out of the equation? So that it would become 5(sin^2theta+cos^2theta). Then that becomes 5(1). Which becomes 5?

You saved my exam mate very helpful thank you a lot

For the 7sin squared = 5 question ( 3rd question) do we need to give the 4 x values because in the question for drawing the graph, it's asking from 0 to 360

if sin^2θ + cos^2θ = 1 then 5sin^θ + 5cos^2θ = 5. isn't that the proof. both sides have been multiplied by 5

Thanks so much this is really helpful for revision!

27:05 Sir, what is happening in this section?

Thank you so much u really helped me

22:10 I understand how you find 57.7 and 122.3 by doing the quadrant method but how do you find the other two values as aren’t the only two quadrants the a and in the cast diagram

THANK YOU

Thank you

thank you

Thanks mate

please do more pure maths video please!!!!

Would you still get the same answers if you use different graphs ?32:25 for example instead of using the tan graph you use either the cos or sin graph?

Thanks

How important is the unit circle for AQA A Level Maths?

I got confused in the second question part B toward the end where we have Sin^-1=√5\7 The answer isn't corresponding with mine How did you get it

top quality mate

at 22:04 your method is very long and gives inaccurate values, on calculator go to MODE SETUP --> TABLE --> f(X) = sin(X) --> START? Type number on the left of X in the interval so that's 0 --> END? Type number on the right of X in the interval so that's 360 --> STEP? Type your value for X then the values will be shown in a table. you don't need a graphical calculator just something like the classwiz, saves time and is accurate

Sir please can we be solving GCE question More often??

Thank you 💖💖

Never skip steps. It’s a bad habit to get into and loses marks in exams…

nice video, but please bring in some more difficult trig identities next time

Thx

17:00

I'm so cooked

11:00 could u not just factor out the 5 and make what's inside the brackets equal to 1 then 5x 1 = 5 ?

23:13

At 27:27 I had worked out the same way, but I don't get how (5x-4) becomes (4-5x).

Endless pain and suffering I am tired

How can 5x-4 be written as 4-5x 27:20

Thanks very much man , ill be sure to share your channel with my friends , if only you did the full a level course

Gosh this chapter is annoying, your explanation helped tho, thanks man

W video

Hi Sir do you think you could cover the quadrant method please?

tired

Where’s r cos alpha vid

Kms

If this is a level maths me is whole alphabet 😂

3;30 mins in and no obviously

roasted

At 11:00, could u not have factorised the 5 out of the equation? So that it would become 5(sin^2theta+cos^2theta). Then that becomes 5(1). Which becomes 5?
