that's cool bro keep doing what you love :)
My phone asked if this is spam!! 😅
@chris brown - How do you know that the acceleration of the two connect objects will be equal?
Thankyou so much this was very helpful for my additional mathematics vectors question
Glad you found it helpful 🙂
Thank you so much you saved my math grade
Glad it was helpful 😌
Could you do double angle formulas and compound angle formulas ect
hey vsauce, michael here
Is this high school math?
Yes, based on the English system.
thanks so much !!
why can't I integrate dv this way; (sec^2x)tanx--->1/2tan^2x... why did we assume that it is secx(secxtanx)?
How do you know that AM and MG are collinear?! You are assuming they are. The point M was supposed to be on OF vector and not necessarily on AG (at the same time).
He was talking about that in the end. If they were not collinear and we assumed them to be collinear, some contradictions should pop up or the equations you get in the end shouldn't be solvable. Here the solutions to the equations in the end have no problem.
Is there a way to do kt with the dot product? I mean like if you were to say the dot product of AB and a vector x,y,z=0 and say the same for AC and for BC then could you solve 3 simultanous equations to get the equation of the normal vector?

Hi, I don't get how you got from y= sec^2x to dy/dx = 2sec^2xtanx??
Hi. The derivative of secx is secxtanx. You can use the chain rule to show this. If y=(cosx)^-1 then dy/dx=-(cosx)^-2(-sinx) which simplifies to secxtanx. Now if y=sec^2x, use the chain rule with u=secx so you have y=u^2, where dy/du=2u and du/dx=secxtanx. Then dy/dx=dy/du.du/dx which is 2u.secxtanx = 2(secx)secxtanx = 2sec^2xtanx. I hope that makes sense.
@@chrisbrown7432 yes it does. Thanks
thank you so much you're amazing !!!

Hi Chris i'm an old boilermaker that has taken on an engineering course at the age of 62(probably not a smart move). These videos are great anyway. I'm working too so dont know how i'll go but made it to 62 so failure doesn't mean anything at this stage of life, because everything is a bonus. Keep up your videos'
Great to hear. Glad the videos are helpful.
Thank you sir that was life saving !!!
Wonderful thanks 👍

thanks ! that helped a lot .
There is a lot of mention about the large obvious statue of Sir Pythagoras, but there seems to be a lack of mentioning of that intriguing and very small (yet realistic) statue sat by that lamp-post in the corner of the frame, I wonder who it is and what they were famous for? 🤔😂
I was scrolling through the comment section, looking for the comments about that magnificent statue by the lamp post. I too am very interested in finding more about that statue, however the Pythagoras’s statue is too, very interesting and majestic.
Unfortunately, Pythagoras was not knighted, probably because he was Greek, so it is just “Pythagoras”. The small statue appears when it wants to, and equally disappears at will. Sometimes it needs to be lured out by offerings of good food and snacks.
