I have been puzzled by this question until I saw your exemplary explanation, thanks a million..
The penmanship ❤️
Thanks!
You just saveme bro! Thanks a lot!
How would you work out how the volume changes if x were to increase or decrease?
THANK YOU SO MUCH!
How did you get the equation in 5:44 ? T-T
he found the derivative of the previous equation
make more video, you are too good at teaching make more please. from Philippines
More to come!
thank you@@mr.premsta6200
where did you get (x - 4)^2 in 7:50 plss
x2 - 8x + 16 is a perfect square
Where did the 96x come from when you did dv/dx
Derivative of -48x^2 is -96x
If x were 1, can I just write it as A=L-2 * W-2?
why would it be between 2 and 5??
why do we expect that x is between 0 and 5? how do we get it?
Fold it by half so since the width of the rectangle is 10, half of 10 is 5. X can't go over 5 as it wouldn't make any sense yk?
Basically x is the length of the corner, so x can't be greater than 10. Since we are folding the box, it can't be like a folded up like a folder so the max is 5
Hi sir, how -35/3 + 16 become 13/3? Thank you
addition of improper fractions
@@mr.premsta6200 Ahh right! Thnk you, Sir!
sir how can i expand i don't understand
How did you ger the-48x thank u
Expand the brackets & collect the like terms
how did he get 16??
By completing the square
