I think you forgot that the earth is a globe/sphere and that paths are curved and very dependent on latitude . . .
👍😁
i love you, like genuinely
Thank you
omg thx sm i was looking for this ahha
😅😅
Thank you! I have an exam tomorrow and never came across a question with descending powers of x and got curious, so this video really helped. Hope you have a good day.
Bro just helped me with my whole homework assignment Thank you so much you made it very easy to understand keep up the great work and I hope you get some traction soon on RUclips
These videos help so much thank you 🙏
love ur vids saving me before a test
good vid
Youre a life saver❤
Please voice it over, we have no idea why you are doing the moves
I will try. Thanks
thank you
😅
Gawd what juvenile GEN Z nonsense.
Lmao, wtf are you on about??? Cool that you know exactly what the horse was thinking....smh, pathetic video 👎👎👎
Thanks
Hi! Please tell me why? P(A|B) -> [1-P(A|B)] I cannot understand
P(B)-P(B)P(A|B)=P(B)[1-P(A|B)], just like x-xy=x(1-y)
@@tutorBesideYou Thank you. I didn’t look carefully.
Thank you
Thank you. I am having problems with complex numbers and this helped me a lot.
Great skills
???????
I got the wrong textbook answer because I wrote initial displacement with the wrong sign
no audio?
Sorry. No
Thank you! Helped alot!
why and how did u switch the order of 4 - 3x to 3x - 4 in the inequality?
I can change their order, because they are in the absolute sign. I have the habit to do in this way, because I feel it would be easier to do the calculation.
It looks my solution matches yours but I don't know why I get wrong answers
if you like, you can send your solution to my email. I will compare ours. Maybe my answer is wrong. Thank you.
no your answer is like the book, so it can't be wrong. but I need some one to explain a bit more. could you explain verbally please? book only had the end answer and not the solution🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏@@tutorBesideYou
@@Athena_Behafarin just understand and use the formula. you can send your work to my email marmot1888@gmail.com. I think maybe you did something wrong in your calculation. It should be a small problem.
thanks alot.I was just looking at this in my math book and now you've just solved it 2 days ago!
how does this help me pass my chemistry test tomorrow
🙁
.... .005x20=.5x.2=.10
Arithmetic Progessions....❤😊
I have never thought I could use the answer for a to solve other options
Thanks I have benefited greatly
This helped make the question much easier, and (idk if this is a feature of the video) but I appreciated how there was no audio, and rather, you got straight to the point.
Thank you so much!
This is not a very rigorous proof. It assumes certain limits exist, assumes the values of those limits and a whole list of things. Although I know what you were aiming for so I'd recommend renaming the video from "proof" to "derivation". Much love.
I thought you’re going to use the definition 😢
Sorry about this
arjun d here - you the goat man!
arjun d - thanks sir this really helped with my jee prep...
This is not a valid proof - use the definition of d/dx next time
For c why is it n^2 not just n?
u1=1, d=2, un=u1+(n-1)d=1+(n-1)2=2n-1, sn=(u1+un)n/2=(1+2n-1)n/2=n^2
tysm, you're carrying my math grade right now 🙏🙏
Just use L'Hopital's rule. ...oh wait.
how u get a=37 and b=-30
3a+b=81, 2a+b=44
Awesome as always. Thnk you.
Okay thank you for your help
Why not just -2 ?
There are also teo complex solutions😊
