In ∆BAD, tan(angle D)=Opposite/Adjacent Or,tan(angle D)=AB/AD From the trigonometric table, tan(30°)=1/√3 Or,75/AD=1/√3=75√3=15m In ∆BAC, tan(45°)=1 Or,AB/AC=1 Or,75/AC=1 Or,AC=75m Or, Distance between two ships=AC-AD=75-15=60m
Sir tq for your best videos. Before i was very poor in mathematics 😌but now I can able to answer any type of questions really they are very helpful sir thank you thank you so much sir
Hi sir am a Nigerian I love your teaching so much your explanation in a topic make it easy for me to understand 💯 Is my answer correct the question you gave us "300m/s"
Sab students apny exams pass karny k sath sath is ko sahi tarah samjhain b warna meri tarah surveying field mein dobara videos daikh k samjhna pary ga..Thanks sir for great help
First position of plane has distance from the point of observation equal to 1500 m and after 10s the distance from observer equal to 4500m and to find speed v need to use d/t formula. Time will be 10s and distance moved at the time is 4500-1500 =3000. Now substituting on formula 3000/10 we get 300m/s as answer
Sir you are explaining physical science and also mathematics amazing mind blowing sir we are appreciating your talent and we hope you continue this for long time thank you for your teaching 🤗🙏🙏💐💐💅💅💅💅 💅💅💅 💅
very nice class, sir what is your writing tool? because the colour look so pretty and I'd like it if you keep using that tool. This is my first time watching your videos, and I find this one worth my time since lot of other teachers take 2-3 hours to explain the chapter but you did it in just 44 min. it was worth it. for the new commers, I would highly recommend this channel. thank you sm!

First we have to find the length between point of observation and the plane before the trip ,then we find the length between point of observation and the plane after the trip. Finally dividing it by the time we get 300m/s. Isn't it?
Sir truely my teacher explained this chapter for 2 times but i did not understand...... In this 44mins with the pictures u have shown and explained i loved it sooo much sir... Thank you😊😍😊😊
The speed of the plane is 300 m/s. Sir, you explain very well by that I can understand class 10th topic in class 8th and solve questions it's questions.
Sir the answer is 300 m/s where x=1500m and y=1500m so, x+y=1500+1500=3000m then by the formula speed=distance/time, time is given 10s and distance 3000m=3000m/10s=one 0 is cancel 300m/s answer....

I needed this from a long time.... Even my school teacher and coaching teachers were not able to teach this good!!!
💖👈
speed of the plane is calculated by the distance travelled by the plane in 10 sec
=(4500m-1500m)/10s=3000m/10s=300 m/s. ok
Got right answer

Most welcome and glad to hear that you are liking them.
Finally a guy who speaks in english
He is a very nice teacher
No other teacher can explain better than him.watching his videos since 2 years
Truely helpful for quick revision one day before preboard : )
I understood the concept clearly
Tqs sir 👍🙏
Great 👍
If it is a tringle with 30°:60°: 90°
The opposite side's ratio= 1:√3:2
And for 45°:45°:90°
Side's ratio=1:1:√2
Such a hard working person thanks for all videos
In ∆BAD,
tan(angle D)=Opposite/Adjacent
Or,tan(angle D)=AB/AD
From the trigonometric table,
tan(30°)=1/√3
Or,75/AD=1/√3=75√3=15m
In ∆BAC,
tan(45°)=1
Or,AB/AC=1
Or,75/AC=1
Or,AC=75m
Or, Distance between two ships=AC-AD=75-15=60m
U are a real mathematics tutor. Thank you so much.
