do you have an electrical background?
thank you mam
Im in high school and my afterschool has extremely complicated factoring
Is there more complicated ones? Like roots and fractions.?
ayayay I thought you're supposed to add with the product rule... Why is she subtracting for the derivative with the e?
Thank you ma'am ❤
Good Explanation cole's , Thanks for simplifying it.. 👍🏻🔥
Thank you so much! I was about to memorize this and the trig integrals and you saved me so much time! Easy to follow and understand!!(:
Ugh, what about nth roots 😢
🎉💫
Ma'am your country has too weak math skills try JEE ADVANCED Mock test so you can test yourself thank you no intention to harm or hurt anyone 😊
Excellent have you done video on Taylor ?
You are a great teacher!
Thankyou ma'am. It's still very easy to understand even after 5 years
Love opening music who composed ? Is there a longer version ?
I like all the math tricks
You've helped me a lot tonight. Thank you so much!
thanks you so Much !! it made it way easier for me to understand the entire Calc 2 xd
Very easy to understand. Thanks!
Thanks Miss🫶🏽
Dlaczego od razu nie wyciągnęłaś 2x przed nawias w mianowniku ?... byłoby prościej...
From India I am in class 6th 😢😢😢
Thank you so much for your help. This is my first time using a Graphing Calculator
You’re welcome! Check out the playlists on my channel for more TI-84 Tutorials.
You are good
Thanks!
Ma'am I think u forgot to put the 1/3 in the right side of the equation.
In the last step, the 1/3 was factored out.
I love you
Great
Thanks! I appreciate the comment!
Can you use this for integrals too? I've notived the integral of cosecx is -ln(cosec + cot) and it works for a few others
Here is a video for memorizing Trig Integrals: kzread.info/dash/bejne/a22L2LaxYpzQpJM.htmlsi=JgGIbAXUjIXuEjCe It uses the same mnemonic device.
@@ColesWorldofMathematics this is golden thank you
thank u!
You're welcome! Thanks for watching!
Your saying the LCD is least, can you help me understand how 3x would be the “least” of the common denominator if x is the lowest value which makes it the lowest value that goes into both
The denominators are 3x and x. We can factor each denominator as follows: 3x (into 3 • x) and x is already in its simpliest form. From that, The unique factors are 3 and x. To find the least common multiple (LCM) of the denominators (LCD), we take the highest power of each unique factor present in the factorizations. Here, we have: 3 (from 3x) and x (present in both 3x and x). Since the highest power of 3 is 3 and the highest power of x is x, the least common multiple (or LCD) of 3x and x is 3 • x = 3x

Thank you very much maam❤
You’re welcome! Thanks for watching.
thanks
You're welcome!
Fantastic
Thank you! Cheers!
Thanks alot I've been having difficulty memorizing this, you just made it a lot easier.
Glad to hear that!
Very helpful!
Thanks!
Great video ! Just to let you know the link to purchase a T-84 calculator does not work.
Thanks for letting me know!
Sinx = -cosx
d/dx [sin x] = cos x
Thanks You from Bolivia...!
You’re welcome!
thank you so much
Welcome 😊
7 years later and it still works
Yes it does! ❤️
I have a doubt that in 2 conditions, With Replacement and Without Replacement. In what condition Should we Use the formula P(x) = nCx · px (1 − p)n−x and in what condition should we just make use of combination in finding probability?
What's the point of integrating "backwards"? It doesn't matter in what order you write those terms.
Thank you❤
You're welcome 😊
thank you i hab test tomorrow
All the best
@@ColesWorldofMathematics Tysm I did well
Thanks
Welcome ❤
wow madam , the sortcut was awesome!
Thanks a lot 😊
Where's the 2 coming from
From the formula.
