Napier's Rules for right-angled spherical triangles

[@elizabethwilliams5025]

I have to learn about Napier's Rule in order to teach my students for an Academic Super Bowl. I cannot believe what an enormously good teacher you are. You also have the most lyrical, gentle voice. Thank you over and over.

[@SteeringMariners]

Thank you Elizabeth, so sweet of you:)

[@NavikRudra]

People please have courtesy to say thanks if you like it.
Thank a lot sir

[@SteeringMariners]

Very kind of you Navik, thank you:)

[@raymondallenjhangiani7670]

Thank you! sir 🙏 very well explained 👍 I never dreamed, I would someday be able to understand spherical trigonometry using the cosine formula for non 90 degree angles in great circle sailing or using the Napier's rules for 90 degree angle or side for G C sailing 🙏 God bless you immensely for all your hard work , effort n devotion to teach others 🙏

[@shivaoraun6922]

Thank you ❤❤❤ I went through my notes but could not understand
After watching that i finally understood the theory as well as question

[@troy0019]

Very comprehensive.
Thank u so much,sir.

[@atulnavigator2318]

Thank you sir for explaining how to make angle in Napier rule

[@ebadahmad2002]

Really helpful video Sir, Thank you for the efforts that you put in.

[@trushnakamble3533]

Sir thank u for making things so easy for us 🙌🙌🙌

[@pennyoflaherty1345]

Thankyou Sir this has been one of my best finds re: trig - I happen to be expanding my math from where it was left many years ago.
I'm currently mapping out " 11 pointed Star " upon a sphere where I do believe this will greatly aide - Trent O'Flaherty

[@nabrajbudha203]

Thank you so much

[@brettAnichols]

I don't know if it helps for anyone else, but if you picture a 3D object inside the sphere (I use a ✈️), when looking at parts of a sphere you can picture the part of the airplane that is in that part of the sphere.
*I'm here as a student of occult magic, for better precision in visualization. This video helped tremendously!

[@jasonturkson42]

A student of what magic ?

[@brettAnichols]

@@jasonturkson42 Mostly the tradition stemming out of the Golden Dawn.
I've been through the Pathworking of the Kabbalah one time.

@@brettAnichols O ok so you're in the practitioner studies I understand now

[@brightawe9002]

Thank you sir.

Thank you very much sir ☺️

Aditya Narkar you are most welcome buddy 😊

Thanks man

Thanks sir

[@stdyturjo9569]

it was really helpful, sir!!!!

[@prinuprasad]

Thank u sir, it's really helped me out. Could u please upload tide calculations of stand and secondary port.and shm method

[@prakashkumar-dk3cr]

Sir you explained very well
Kindly put one numerical part for PZX trangle for finding observers position

[@yashnagane6688]

Thank you sir

[@milind5726]

Sir,
Here in this video ,you havent added a negative sign in tan adj formula, but in other video you have added.

[@SteeringMariners]

you add negative sign only for quadrantal triangles (where side is 90) not right-angled spherical triangles.

[@MOHITSHARMA-ue8el]

thanku soo much sir

[@vasilulde]

Thank soo much sir❤

[@dev7020]

Thanks

[@kgs1878]

U r the best sir...

[@SteeringMariners]

Thanks buddy, very kind of you:)

[@gurpindersingh3223]

Hi, thank you, it’s been explained very well, but there must have been atleast a little mention about how to go about solving the triangle with one of the “sides as 90 degrees”.

[@SteeringMariners]

You are right Gurpinder. I will make a video on that topic soon:)

[@bigfatshit8186]

If I recall, that is called Quadrantal Spherical triangle

[@amruthaprakash6261]

How this napier's rule is related to crystallography?

[@sakeyrajesh9238]

There is any book for this ?where it available,can u send me reply

[@SteeringMariners]

I am sure there are books out there on Napier's rules and spherical trigonometry but I am not aware of them. Sorry.

[@nitesh1906]

Yes... U can get a book from Nutshell publications.. Spherical Trignometry by Capt.H.Subramaniam.

[@nitesh1906]

Sir... Sometimes we solve the Ambiguity cases... And we get 2 answers for one angle like 80deg OR 100 deg... How to resolve this ambiguity?

[@abraaaa]

هل يمكن أن تعطني اسم المرجع مستخدم في الشرح

[@sgiri2012]

Sir,I have a doubt in middle part. You said that it is 90-a. But there arises a confusion that whether the angle A is also supposed to be the middleone. Thats it sir

[@vickyjha2833]

Kindly explain formula when side is 90 degree

[@Rabicr74]

Sir we can't take value of C = 90

[@muhammadibrahiem178]

love you sir
you are a great teacher.
may Allah bless on you ameen

[@SteeringMariners]

U r very kind 🙏🙌😊
