Thank you for your help
My grandchildren will be sung lullabies about what you have done for me today
I can’t believe this question tripped me up during my calc exam 🤦🏽♂️
THANK YOU!!!!!
Thanks a lot for the explanation!!
Can you please make a video explaining the symbolic translation of conditional and biconditional statements:basic
danke
y+8(1)=8 ? not 9, right?
Yep. Mistakes happen occasionally. Thanks for letting me know.
just to verify, 2u+6 divided by 2 equals the u+3 which turns to v=-3 correct?
Newton-Raphson
thank you sir please continue for more math videos
Easy to understand, great job sir! My homework is finally done❤🎉
Loved this video ❤❤ and how simply you explained everything. Keep it up😊😊
I love this guy! I'm a 12-year-old studying for a competitive exam, and I was just told the day before the exam that math was involved too. I just saw this guy's vid, and boy it is so damn simple and good. Thank you so much!
Thank you for this video you explained it extremely organized!!
Your example seemed to be the only one similar enough to be proper for these types of math problems across the internet and in course material! 5 stars!
where does 212 fit? this was very simple until it wasn’t
fantastic.!! thank you
bu ne amk
Wish audio louder You seem very lucid !
Can you solve the integral manually without using the calculator please
Não dá. Esta integral é muito difícil de resolver. O melhor é usar método de aproximação.
Thank you so much this helped me alot
Thank you so much!
Very easy 😂
Thank you- I could not grasp this after tons of practice in Aleks. You finally explained it in a way that clicked- “has less elements than the original set…” etc. BLESS YOU
Thank you so much!!!!
Thank you sir you saved me
Don’t you mean dx/dθ = 5/3 sec θ tan θ instead of dx = 5/3 sec θ tan θ?
Yes. It should have read as dx = 5/3 secθ*tanθ dθ
what if one of the sides is rectangular? like a kitchen exhaust
can you also do it using like 2 functions where its (f(x) - g(x)
Im prettu sure you're looking at the washer method for that
TY I WAS SO CONFUSED ON THIS
How do you go from 22 to 100? Can you explain please?
Hello Ruben. Sure thing. In base 10, which is our normal base, the biggest number you can put into each digit is 9. If you get larger than 9, the number becomes 2 digits which means it can no longer fit in one digit space. Likewise, in base three, the largest number that can go in a single digit is 2. So 2 is the largest number you can put into a single digit. If you add one more to this 2, it does not become 3, because we are in base 3. Instead, the next number becomes 10. The digit to the left goes up by one, and the digit to the right goes back to zero. So in base three, you can count like this. Notice that there are no numbers bigger than 2. 0, 1, 2, 10, 11, 12, 20, 21, 22, 100, 101, 102, 110, 111, 112, 120, 121, 122, 200, 201, 202, 220, 221, 222, 1000..... I hope this helps. Take care!
Nice explaination sir
Thank you for your positive feedback!
Sir pls make video on AM ,GM, HM inequality
Tysm I'm dumb in maths
THANKS AGAIN LOL!
thank you so much!!!
On problem 4, when you first start it and distribute the 4 outside of the parenthesis to the inside numbers, do you also need to distribute it to the -4log2w?
That is correct. Thank you for letting me know about this.
thank you @@Kratzmeyer
SIR THANK YOU SO MUCH
find the surface area of the object obtained by rotating y=sin(2x), 0<=x<=pi/8 about the x axis
Thanks for your video it helped me with my homework
Thank you! This was really helpful
i just confuse about gauss but thanks to you, now im know why

Excellent video, except for the 64 we did not need to use. Unless I am missing something, -(-64)(-1) does not = 64. Luckily we did not need to use this number.
If a calculator isn't available like on a test you could have used inverse tangent to solve for theta and get the same answer
Thank you for your video. I'm taking Math online, and the written examples given to me do not explain the "why" the number of elements on the left must be on the right to make it true, or if there are fewer elements on the left than the right, the answers would not be true. I don't know if I'm explaining myself, but I hope you kind of understood. Your video was short and clear. I understood everything in only minutes.
I would never survive math if not for your video's
Excellent videos
Thank you so much😢😢
thank you for being the first thing i found that confirmed my method!
