Sir is it not 18:40 -10:00 where is 22:00 coming from?
08:10 Has the question you are asking. 22hrs is gotten from the time 10pm.
Well explained
Thanks❤

good vid G
From Kenya ,thanks coz i get to understand better
Awesome❤
I swr this is perfect I love this ❤❤
😮😊thanks again to you
❤
Thanks so much for your time and I have understood very well in pendulum
Finally I got to know how these degrees are taken😮💨😮💨❤️
Great
On example 3 it says find the time of the pendulum. Now what if they say find the period of frequency? Please make a video on that
The explanation is top notch
Thank you very much for this topic have lean a lot
Your video has helped me i have no where to learn,i now understand this this topic clearly thank God he has shown me the way to u,🙏🙏🙏 continue with the good work
Sir your appline

Thank you so much. This video helped me to understand the concept very clearly , I was afraid that maybe I will never understand the concept of angles on earth but your video saved me. Once again thank you so much!!! Love from INDIA🇮🇳🇮🇳🇮🇳
Nice ❤
His vid is so helpful🎉❤
Thanks more
One of the best explanation videos on pinhole cameras!!!!! Thank you so much!
I blame RUclips for not giving this video views 💔like this is one of the best so far ❤❤❤❤❤❤❤❤❤Thank you so much sir❤❤just expressing how grateful I am ❤❤❤
Well presented 👏👏
Trigonometry 2019answers
Which question?
2016 paper y did we change the formula for distance of latitude is it because we found the small r thats y we live cosx?
Distance along a latitude and distance along a longitude use similar formulas. DISTANCE(d) FORMULA d = (theta/360°)×(2πR) theta = angle between two points on circle R = Radius of circle For the first question on distance, theta = 360° and R = radius of latitude 50°N. Now radius of latitude = radius of earth × cos(angle for latitude). Because the radius of latitude is not same as earth's that is why formula changed. Also, the first part was not included because 360°/360° = 1. For the following question, theta = difference in longitude and R = radius of longitude (earth).
Would like to know the name of the software that you used to do the presentation
Krita is the app we use to do the writing.
Nice presentation
Thanks 🙏
Thanks for the information
Is not that when u have difference of two points in the hemisphere we had the numbers,try to reverse yo explanation
Check the reply to the pinned comment. Hope that answers your query
It was really helpful
Thank you very much for your help God bless you
I have enjoyed the video sir good teaching.
what if you are given 2 non right angle triangles with same area
I have a question about the topic
You can send it to zedonlineschool@gmail.com
this is was excellent explanation thank you very much for your help
Thanks❤ sir
God bless you sir the work you do is invaluable
Thank you so much for the lesson. I personally have enjoyed
Beautiful
Nice explanation sir
Very well explained. Thank youvery much from India🇮🇳🇮🇳
Thanks for sharing! I posted a short video on deriving the law of cosines, It should apply for all angles (acute, obtuse, reflex, negative). Hope to get your thoughts.
Yes it surely should.
You explain so well why the shit views are so less,..☹️☹️
Thank you so much brother.. it helped a lot
The best teacher thx 4 d tip
Great job sir
