2024-05-14 19:37:40 +0000 UTChey, i was wondering whether you could update the worksheet for 2023? since the latest exercises in the worksheet are from 2020

2023-10-25 16:21:19 +0000 UTCThis 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

2023-08-09 13:26:54 +0000 UTCYup looks a lot easier now. i see, you just have view it at a simpler angle Aight got it. Thanks jacob. Sick worksheets btw.

2023-07-22 03:34:54 +0000 UTCI'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?
Intuitive
2023-07-22 03:20:09 +0000 UTClike other than multiplying with e^x
Abdur rahman
2023-07-22 03:01:10 +0000 UTCWhat do you mean?
Intuitive
2023-07-22 02:59:44 +0000 UTCand lastly is there any other way to do this question?
Abdur rahman
2023-07-22 02:59:02 +0000 UTCAs long as it makes sense mathematical you're good. Remember "e^-x" is "1/e^x" same thing.
Intuitive
2023-07-22 02:58:43 +0000 UTCoh 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.
Abdur rahman
2023-07-22 02:55:37 +0000 UTC(e^x)(e^-x) = 1
Intuitive
2023-07-22 02:33:46 +0000 UTCI times through by "e^x" to get rid of the "e^-x".
Intuitive
2023-07-22 02:33:27 +0000 UTChey jacob, for q19 why did you multiply e^x to the 4(e^x)+4 ? cuz we already have a e^2x after simplifying.
Abdur rahman
2023-07-21 17:36:23 +0000 UTCfor q18 isnt it supposed to be e^x - e^-x but you did +

2023-02-13 06:09:23 +0000 UTChey!! was wondering, what type of graphic tablet do you use?

2022-05-14 06:56:44 +0000 UTCYes I guess that works but I would recommend always taking logs for practice when you encounter equations of higher complexity.
Intuitive
2022-05-14 06:28:59 +0000 UTCNo problem brother
Intuitive
2022-05-14 06:27:27 +0000 UTCthank you sm for the videos btw!! youre the reason im gonna ace โค๏ธโค๏ธ๐
lamia billah
2022-05-13 11:04:19 +0000 UTChey, 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
lamia billah
2022-05-13 11:03:00 +0000 UTCHello 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 .

2022-04-12 13:55:44 +0000 UTCI'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.
Intuitive
2021-09-28 09:47:56 +0000 UTChello just want to ask which is the chapter where you need to sketch exponential graphs? or is it not included anymore...
good boy
2021-09-28 06:44:59 +0000 UTCYes that's a mistake thanks for pointing it out :)
Intuitive
2021-09-24 20:49:27 +0000 UTCThank You
Intuitive
2021-09-24 20:46:10 +0000 UTCThis worksheet was done amazingly.... The way you progress through out the worksheet is so smooth. appreciate it man.
Mohammad
2021-09-24 20:32:43 +0000 UTCUh 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
Ally A
2021-09-18 20:02:05 +0000 UTCI 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.
Intuitive
2021-09-18 19:51:19 +0000 UTCHey 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?
Ally A
2021-09-18 17:37:49 +0000 UTCYeah man pretty sure it was this: https://youtu.be/jXZAbnn1kTU

2021-07-15 10:51:22 +0000 UTCCan I have the music you used in this video
MARCO
2021-07-14 19:52:30 +0000 UTCIt seems to be working well now, I can see the log/exponential video. Thank you!

2021-04-06 08:37:10 +0000 UTCIโve recently upgraded all my videos to make them exclusive to patreon. So itโs actually really helpful when people point things like this out.
Intuitive
2021-04-05 20:08:10 +0000 UTCReally? So no log/exponential question? Are you watching on you pc or phone just out of interest.
Intuitive
2021-04-05 20:05:30 +0000 UTCHi, this could just be me, but Iโm not seeing the log/exponential question video. Instead itโs the differentiation video with the log/exponential title. :)
