Too late for meππ

I hope he does that soon

hey, i was wondering whether you could update the worksheet for 2023? since the latest exercises in the worksheet are from 2020
fares exam
I agree he is the best

This video is everything; I tried revising logs using the textbook but it confused me more and your video cleared up and simplified everything:) this subscription has officially been my best investment to date

Love the content! Im the new patron here. I wish you success

Yup looks a lot easier now. i see, you just have view it at a simpler angle Aight got it. Thanks jacob. Sick worksheets btw.
Intuitive
I'm just simplifying the expression by multiplying through by the denominator? I think because it involves e^x which confuses you, if the expression was this instead "x + 1/x = 4x + 4", then simplifying this would be easier for you?
Abdur rahman
like other than multiplying with e^x
Intuitive
What do you mean?
Abdur rahman
and lastly is there any other way to do this question?
Intuitive
As long as it makes sense mathematical you're good. Remember "e^-x" is "1/e^x" same thing.
Abdur rahman
oh but i just made e^-x to 1/e^x and in that way u get rid or e^-x and get e^2x plus 1. Basically the same thing you did except the multi of e^x. anyway i kinda did get the correct ans but its positive instead of -ve.
Intuitive
(e^x)(e^-x) = 1
Intuitive
I times through by "e^x" to get rid of the "e^-x".
Abdur rahman
hey jacob, for q19 why did you multiply e^x to the 4(e^x)+4 ? cuz we already have a e^2x after simplifying.
kushi
for q18 isnt it supposed to be e^x - e^-x but you did +

hey!! was wondering, what type of graphic tablet do you use?
lamia billah
got it boss! ty
Intuitive
Yes I guess that works but I would recommend always taking logs for practice when you encounter equations of higher complexity.
Intuitive
No problem brother
lamia billah
thank you sm for the videos btw!! youre the reason im gonna ace β€οΈβ€οΈπ

hey, instead of taking logs on both sides, are we allowed to just plug it in the bases so we get the direct value e.g 2e^2x=5 can be directly written as 2x= ln5/2 without taking logs on both sides

Hello thx alot for the videos .. just wanted to ask about the last question . I tried solving it by doing u=e^x . From the begining . That's simplifies everything . And got the same answer .
Intuitive
I've barely seen it. The only place I have seen the sketching of graphs such as e^x and ln(x) is in the numerical solutions question. So have a look at that. You should know the basic shapes of these graphs but it's pretty minor.
good boy
hello just want to ask which is the chapter where you need to sketch exponential graphs? or is it not included anymore...
Intuitive
Yes that's a mistake thanks for pointing it out :)
Intuitive
Thank You

This worksheet was done amazingly.... The way you progress through out the worksheet is so smooth. appreciate it man.

Uh no I'm talking about 10 (b). You wrote u = e^2x but then you later used u = e^x. Is that a mistake, or am I just dumb idrk
Intuitive
I just checked. Ummm I see no mistake are you talking about the end of question 10 (a)? Cause I just multiplied through by e^x, then simplified, then multiplied by e^x again.
Ally A
Hey man idk if I'm tripping or what, but I think you made a mistake in question 10. You wrote e^x, but isn't it supposed to be e^2x?
Intuitive
Yeah man pretty sure it was this: https://youtu.be/jXZAbnn1kTU

Can I have the music you used in this video
Ines
It seems to be working well now, I can see the log/exponential video. Thank you!
Intuitive
Iβve recently upgraded all my videos to make them exclusive to patreon. So itβs actually really helpful when people point things like this out.
Intuitive
Really? So no log/exponential question? Are you watching on you pc or phone just out of interest.
Ines
Hi, this could just be me, but Iβm not seeing the log/exponential question video. Instead itβs the differentiation video with the log/exponential title. :)
