I enjoy your calmness in teaching these math problems. Even tho I didn't learn some stuff you explained yet I still somehow find it fun to watch you do them. Keep up the good work, Profesor!

This is below a neon evangelion op with congruent lines. I'm a lil ashamed that I completely forgot what the law of Sine was until the formula showed up.
This would have been a nice video too see before my final geometry exam. Of course, it seems kind of common sense, do I should have been able to figure this out myself.
Given: 11*x^2 - 296*x + 484 = 0 Recognize this as a quadratic equation in the form of: a*x^2 + b*x + c = 0 The general solution is: x = (-b +/- sqrt(b^2 - 4*a*c))/(2*a) Plug in a=11, b = -296, and c = 484 x = (296 +/- sqrt(296^2 - 4*11*484))/(2*11) x = (296 +/- sqrt(66,320))/22 Use trial and error to find square numbers that divide into 66,320. The best we can do, is 16, so divide by 16, and bring 4 out in front. x = (296 +/- 4*sqrt(4145))/22 Cancel a factor of 2 from top and bottom x = 148/11 +/- 2/11*sqrt(4145) That's as simple as you can get it, and still keep the exact solution.
It's convention for either capital letters or Greek letters to stand for angles, and corresponding lowercase letters to stand for the opposite sides when using this formula. You of course can do it either way you see fit. Whether you use: sin(A)/a = sin(B)/b or a/sin(A) = b/sin(B) it makes no difference. You can flip both sides and it's the same equation.

Thank you. I appreciate the encouragement!
Greetings from Iran. From easy to complicated and always instructive.
Thank you, Professor. I received a message. I am still working on "Sequential Projection".
Cramming for a test atm and was extremely stressed. This made everything make sense, thank you!
Greetings from Venezuela 🇻🇪 Thank you professor.
You are very welcome
Love these shorts

When all hope was lost I came to this video and now I understand😅
thanks professor!
Thanks!
Wonderful!
I really love math❤❤❤Ty for that video
I love so much math ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤ thanks you so much
bro you just saved my life

Does it apply to any side of the triangle?
Like missing side AC will equal to the Sine of angle B?
Yes~

11x2 - 296X + 484 =0 Sir how to solve this easily ?
Given:
11*x^2 - 296*x + 484 = 0
Recognize this as a quadratic equation in the form of:
a*x^2 + b*x + c = 0
The general solution is:
x = (-b +/- sqrt(b^2 - 4*a*c))/(2*a)
Plug in a=11, b = -296, and c = 484
x = (296 +/- sqrt(296^2 - 4*11*484))/(2*11)
x = (296 +/- sqrt(66,320))/22
Use trial and error to find square numbers that divide into 66,320. The best we can do, is 16, so divide by 16, and bring 4 out in front.
x = (296 +/- 4*sqrt(4145))/22
Cancel a factor of 2 from top and bottom
x = 148/11 +/- 2/11*sqrt(4145)
That's as simple as you can get it, and still keep the exact solution.
shouldn’t it be A/sina?
It's convention for either capital letters or Greek letters to stand for angles, and corresponding lowercase letters to stand for the opposite sides when using this formula. You of course can do it either way you see fit.
Whether you use:
sin(A)/a = sin(B)/b or
a/sin(A) = b/sin(B)
it makes no difference. You can flip both sides and it's the same equation.
Please make your decimal point prominent
Please show how you completed the last step please.
I had completed the last step on a calculator
@@mrhtutoring it is not supposed to be applied AT right angle for sine law?
@@yerui8978 Law of Sine is used when the triangle is not a right triangle
@@mrhtutoringthanks
