while the process is right, your solution to the first problem is wrong. It is 0.245 N not 0.229 N
Thanks for visiting my channel and pointing it out. I might have done some miscalculations. I appreciate your attention to details.
I am so confuse to identify order and degree yet, but now it is clear and understand easily

Thank you for visiting my channel.
I think there's a mistake, the unit of volume should've been gm/l ,but you calculated the normality using gm/ml ...
Thanks for pointing it out however I converted liter to ml.
Your solution to Q2 is wrong conversion of ml to litre
Thanks for visiting my channel. I appreciate you pointing out any correction, but I am sure it is correct because 1 litre =1000ml so 1ml =1/1000 litre and this is the conversion I used. I am not sure which part you are saying is wring.

Great video, though I have a problem, if you were asked to find the limit of |cosx|/x as x approaches 0, what would your answer be?

Milli is 10^-3

Find limit tan(x-2)/x^2-4 when x approach 2? How can i solve this problem Btw x approach 2 not zero
@@DRMath can i use lim x->2 Tanx/x which equel 1 or it works only when x approaches to zero My teacher didn’t teach me about L’Hopital’s rule yet. I’m new to the derivatives
Thank you excellent explanation
Thank you so much..
Thanks for visiting my channel.
Very helpful tricks, good job, sir
That's a great video thanks. I came to watch this after researching how 1 metre is defined. It originates from - The total metres from the north pole to the equator = 10,000,000 metres. 1 nautical mile is 1 minute, which in km is calculated as 10,000,000 / 90 (for 1 degree) / 60 (for 1 minute) = 1,851.85 metres, the same as in your video!

What is wrong if we specify distance in kilometer or mile as we do on land?
I believe it is due the long distances we travel in sea and air.
Why is the slope of the radius y-y1/x-x1, I thought they changed the order in the denominator, thanks bro
What ever order you have In numerator use same in the denominator.
I'm really having trouble with this. The last guy said 1 Nm is equal to 1 minute of degree based on the circumference of the earth at the equator. Your saying it's based on 1 minute along a line of longitude. But your distances would not be uniform due to the Earth being an oblate sphere. In other words, a Nm closer to the poles would be longer than a Nm in the tropics. This is because, due to the oblate shape, the radius of a certain arc increases as we approach the poles and decreases as we approach the equator. Hence the distance of one minute is longer relative to the longer radius of that certain arc that is closer to the poles. OK, that's it, I'm going to bed before I launch my turret like a T72.
