I'm a software developer now but never understood these concepts in my school but now got 100% clear. Thanks a ton buddy

[@codebasics]

😊👍

For who is wondering why this fixed mapping exists, it's because circles. Angles imply circles in which triangles reside, so the hypotenuse is like a bowstring and the imagined outside of the circle is the bow. Circles are always the same angles regardless of size (360 degrees by definition), which is why these "law of nature" ratios exist. The law of nature is basically "circles exist".

I wish this existed 14 years ago during my high school times :'( :'(

[@RaahgirHarshal]

I first time watched trignometry lesson with interest and understood these terms.....Thanks a lot....

[@qicai3682]

your clear and humorous way of explaining math always gives me a smile!😄

[@nikhilkulshrestha213]

first time ever seen these type of teaching skills

[@TheAtef]

It's literally my first time REALLY understanding what tan represents!! Thanks a lot man!

[@srikrithibharadwaj6779]

Eagerly waiting.. I’ve learnt these concepts during my 11th,12th and graduation, but not even once I’ve used this in real time.

[@SAYYEDASGAR-hd7go]

And plz complete the playlist it is vey helpful

[@Blannwich]

Thank you, your discussion of natural law has finally helped all of this click for me.

[@GF86123]

Best explanation all over the internet.

[@krishnakumar-ye9kp]

Your videos always having best content than others and your main intension is to share the knowledge not make money by posting videos. But there are few KZbin channels and their main intension is making money by posting unnecessary videos daily without fail.

However, the basic principles of using trigonometric functions to find efficient force or angle are the same. Once we know the angle of the rope, we can use trigonometric identities to find the efficient force or angle. For example, if we want to find the minimum force required to drag the box, we can use the sine function to calculate the sine of the angle, and then use the inverse sine function to find the angle that corresponds to the minimum force. Similarly, if we want to find the angle that requires the least amount of work to drag the box, we can use the tangent function to calculate the tangent of the angle, and then use the inverse tangent function to find the angle that corresponds to the least amount of work. The sine function can be used to find the ratio of the opposite side to the hypotenuse of a right triangle. In the case of dragging a parcel box, the opposite side would be the distance between the box and the point where the rope is attached, and the hypotenuse would be the length of the rope. The sine function can then be used to calculate the angle between the rope and the ground.

stupendous fantabulous fantastic magical😃 I really appreciate your work

[@tomsebastian9743]

I can give you only one 👍. But I would like to give more. Really appreciated bro.

[@RivinduBRO]

Appreciate this explanation. Please continue this series

[@rajraja4383]

Additional point Tan =sin/cos

[@pveeranjireddy8959]

Thank for making data science math videos

[@SaifSkills]

You are Excellent teacher, thank you so much, blessed having such a wonderful teacher love from pakistan

[@alizeze5802]

You are realy a good teacher. Thanks alot. I realy appreciate your work.

[@zeph7691]

this is really helpful to visualise the real life application of these ratios, thank you!

[@josefrancis3714]

Very smart and interesting! Keep it up!

[@jyoti_kumari36]

Sir is there any way to find out that for which angel which ratio should be used ... please sir tell me and if you have already uploaded these kinds of video then please give it's link or playlist

[@nilakantas5153]

Hi sir waiting for ur video

[@nilakantas5153]

Nice explanation Sir 👌🙏

[@aravindaravind6658]

Thank you sir...

[@jeanclaudeho2222]

amazing content, thank you!

[@mwauraerick]

what kind of instrument would measure the inclination towards the top of the tree

[@Leopar525]

Thanks masta

[@wongyara1]

thank you so much (thailand)

[@AT-vw8tc]

Hello sir, Can you please tell me which applications do you use to make those explainer videos and any resources for the graphics? Thanks.

[@vickyv6747]

School Teacher are the only reason who makes kids hate maths..I wish if my classes were like this when I was at school....Most of the school teachers are national wastes, who just creates traumatic experience for kids...This should change

[@Be_shant_]

Sir Plz Start A Math Class Plz...

[@pveeranjireddy8959]

If not studied in high can learn now?

[@WILSON.1]

How does he find the angle?

[@ankurhalke139]

Ohhhh man . I just learn this for free. I wasted my 10th tution fee of 10k and so much of headache and time ...........

[@codebasics]

Glad you liked it

[@manjunathyelipeta1456]

If sin is opposite side /hypotenuse in a right angled triangle the how can sin have negative values since distance /distance is always positive

[@ankit.chaurasia]

Your question don't make any sense. Try learning Basic maths it was there in 8th Std. Sin won't have negative values unless you are dealing with negative numbers, which in here case not possible. When you say sin 270 = -1. Here the opposite side's displacement is *assumed* to be negative.

[@ankit.chaurasia]

When we say something negative. It is always assumed and opposite to actual value. Like i will get -10rs. In English it won't make any sense. But in maths it means you have to give 10rs. Like how people say his companies profit went negative they actually mean that the company is in loss. So at 0:38 for the man's sin angle is positive right now. Because height of tree is + and hypo is +. But if i assume the tree to be inside ground with same height. The angle goes anticlockwise or in other sense the height of tree goes negative. So -opposite/hypo = -sin angle.

[@ritikadubey3798]

Sir why did u stoped making videos in this series!

[@codebasics]

I have not stopped. There is some delay due to other priorities.

[@ritikadubey3798]

@@codebasics ok sir ... Thanku for your reply .... Just remember ur students r waiting 🙂

[@utkarshashinde9167]

but why sin came into picture , havnt answered that sir

[@sachinkulkarni6956]

And in school I thought this is SCAM

[@neerajverma9226]

Please simply Gradient Decent

[@pawanchawla160]

2+3 =5 is not law of nature, it is a law of human. I mean, nature did not say this but human says that 2+3=5.
