Finding the Area under a Curve
We try to build an intuitive understanding of how to find the area under a curve as we build up to using the summation of many rectangles.

Indeterminate Forms and L'Hopital's Rule
Thank you this helped a lot!
no need to approximate the secant between 2 and 4 and say "close enough" since u know s'(x) is increasing on the entire interval and positive so s'(3) is between s'(2) and s'(4). good explanations and problems tho :D
i was here
studying this for my math test rn
Thanks man
This video was very helpful thank you.
Thanks, this really helps on finding the radius.
couldnt have you used l'hopital theorem
Thank you.
Key inverse ke aage kya lika hai
Thank youuuu
best tutorial in the platform
do you need to mod 26 it? you seemed to skip over that part
best video on finding error . thank you very much👍👍👍👍👍👍
Helpful video until 6:26 after that the problem was just extremally stretched. you can just multiply 2/n by the function and use the i formulas and get the answer much easier.
Great job on seeing that! That is another way to go about simplifying the problem, and would save a few steps!
It is very halpful
Helpful !
i realy amazed at this video
goated frfr
Seriously bro your a life saver
Hello sir can you pls explain the simple matrix encryption scheme also known as ABC matrix encryption scheme.
Thank you so much
this was so helpful!!! thank you!
I was struggling trying to figure out the radius on my own but this really really helped. Thank you
What if we start by finding the derivative with respect to y instead of x
H, the height of the partition parallel to the axis of rotation, should be subtracted by top-bottom, not right-left. Right-left is for when the axis of rotation is horizontal, as the partition will be laying down instead of standing up.
Is it used in whatsapp sir..
A similar concept would be used in the sense of needing a key and key inverse, but something much more sophisticated would be used by WhatsApp to ensure it is protected against brute force attacks. You can look into AES and RSA encryption if you want to learn a little more about industry level encryptions
How you find key matrix sir..
key matrix will be given...if not then assume an unit matrix as key matrix...
ur the goat bro tysm
Helpful
Thanks got a geo test on this and our teacher hasn’t taught us anything (like parents ar emailing the principal kinda bad) so this is really nice to be taught this in depth
Epic vid
Thank you so much for explaining why you would use shell not disk
Also including how to check!!!!
What if i have the plaintext and the ciphertext and i have to find the matrix and the hint is a 3x3 matrix
If I am understanding correctly....we could find the key matrix like this: Since K*M = E where K is the key matrix, M is the message matrix, and E is the encrypted matrix We want to solve that equation for K since you are trying to find the K Therefore, take the inverse of M on both sides K*M =E K*M*M^-1 = E*M^-1 <--Remember to multiply on the right side both times, matrix multiplication is not commutative K*I = E*M^-1 <---Matrix times its inverse is the identity matrix (I) K = E*M^-1 <---Anything times the identity matrix (I) is just itself So then we have the equation to find the key.....multiply the encrypted matrix times the inverse of the message matrix
amazing explanation man !!! thank you :)
hello sir pls what happens if I instead use 0 as space then bigin A as 1 then z as 26? is it Soo bad?
Everything would be the same except that which numbers assigned to which letters would be shifted one...like you mentioned. 0 = space, 1 = A, 2=B, .... 26=Z. It would still work the same!
Thanks so much man, Ive been searching for hours on what to do when a specific number axis is given but couldn’t find it anywhere, thanks for all ur help
Glad it helped!
Thank you for the great explanation
you're amazing, you helped me out in desperate times
Nice presentation. On a side note, I finally know why directional unit vectors start from i.
Glad it was helpful!
OMG!!!! This held soooo much!!!
I really appreciate this video! THANK YOU
This was really helpful. Awesome explanation
This was extremely helpful thank you!
Perfect video. Just what I was looking
Thanks man you helped me out of a rut
Thnkieee sir
I’ve got mad props to anyone who understands and solve this equation. God blessed me with the talent to draw, I wish I was blessed with the ability to understand math instead, lol.
Awesome video. Made my Calc II homework a bit more bearable.
Awesome! Thank you for this video! I've been interested in the Aliquot Sequence ever since I became aware of Amicable Numbers ans Sociable Numbers. I stumbled across all of this while trying to find Perfect Numbers on my own. I discovered Mersenne Primes along the way (doing my own research) and then found out that all of this had all been done previously. :-) Anyway, I had never heard of Aspiring Numbers, although I had discovered the numbers that lead to Perfect Numbers. Now, I know what they are called! Love it!
this was very helpful, thanks!
