Hi I wanted to submit an assignment, it's showing an error message that you can not submit assignment before the due date
Give it some time and try again.
@@demojmathsandsciencetutors thanks I have submitted successfully
Thank you sir,now i understand the system of repeated factor of the denominator om 0ar6ial fractions.🎉🎉🎉
@@PrinceChibueze-o1c I am glad
But for someone like that doesn't have a laptop, can i write my codes in a document file and just submit? Unless there is Jupyter lab for phones too like the PC You mentioned something visual studio code.
I am also a student, its only the 3mtt officials that can clarify if you can just write it on a document file. The Visual Studio code is a coding platform like Jupyter lab.
@@demojmathsandsciencetutors Alright thank you. I only asked because i typed out the code on a document file and submitted. I used a python application on my phone for it
@@Yusufemrys ok. Kindly share the name of the Python application you used on your phone. I am sure some other guys reading our conversation will also want to work from their phone
@@Yusufemrysyou use pydroid or termux right??
Thank you Very much for the update. ❤
You welcome Abubakar
great topic, thanks 👍
You welcome
mast ha 🎉🎉 sir
Thank you, I guess you speak Hindi
Well done guys!
Thank you 💕
Try to explain on fy 1 sir .I thought it would be 300sin30
It's 300cos30. The angle is between fy and hypothenus. So that, cos 30 = adjacent/hypothenus. Cos 30 = fy/300. Then, fy =300cos30
In the last example why didn't you replace the π with 3.142
I guess you are referring to linear speed where I left the answer as 60pi cm/s. Obviously, you can change the pi to 3.14.
@@demojmathsandsciencetutors ok
Nice sol
Thank you
can w^2 = V^2/r ?
I apologize for my late response, w^2 is not same as V^2/r. Remember that v =wr and w = v/r and a = v^2/r
I like your voice ❤❤❤
Thank you
Please is o a number?
No, o is an alphabet. Not a number
@@demojmathsandsciencetutors but you kept using it as a number
@@TalesWithIvyno, I said 'zero' which is a number 0.
You are not using the formula for height
Thank you for your comment and observation. I did not use d direct formula. I resolved the velocity into horizontal and vertical components to help student understand the concept from basics
Thanks it makes the concept clear
Glad to help, good show
Thank you
X=9
Great
Great work again. I love your explanation. Keep it up brother.
Thank you for your word of encouragement. I deeply appreciate
Another method. Let the two radicals be an and b respectively. Then a-b=2 and a^2-b^2=12. Or (a+b)(a-b)=12. Substituting and solving you get a=4 Substituting in the first radical for a you get x value as 9. Could do it in the head.
Very good! This is one thing I always love to see in mathematics. Many ways to solve a problem
Well done brother
Thank u
You know how you did not actually solve it, right? The idea is not bad, and you can proceed with it, but the original question has 2 possible solutions, and you have to work a bit more for them.
Thank u for your feedback. The second solution leads to undefined. That is why I did not mention it. In subsequent lessons, I will take note.
How to Solve Radical Equations: √(x + 7) - √(x - 5) = 2; x = ? First method: √(x + 7) - √(x - 5) = 2 = 4 - 2 = √16 - √4 = √(9 + 7) - √(9 - 5); x = 9 Second method: √(x + 7) = √(x - 5) + 2, x + 7 = [√(x - 5) + 2]² = x - 5 + 4√(x - 5) + 4, 4√(x - 5) = 8 √(x - 5) = 2, x - 5 = 2² = 4; x = 9 Answer check: x = 9, √(x + 7) - √(x - 5) = 2; Confirmed in First method Final answer: x = 9
This is great. I like ur second approach. It is generic and highly intuitive.
√(x + 8) + √(x + 1) = 7 is solved by inspection. 4 + 3 = 7. How do you get to √16 and √9? x = 8.
Hello Jim, thank you for your enquiry. A simple way to text your answer is to substitute your value for x in the equation . In my next video, I will demonstrate it. But if you need further clarification do hesitate to ask or send me a mail. I will be glad to help out
I'm first🤭
Yes you are! Thank you. I hope u will hit the subscribe button
Prof. How are you doing. Great work again. Keep it work. Kind regards John @askjofa
