I've always had trouble memorizing all of the rules for the ambiguous case, but now I don't have to memorize anything! Thank you for making my life so much easier!
THANK YOU SO MUCH! I know this video is 4 years old but I just watched it while studying for an upcoming test, I finally feel like I UNDERSTAND everything I learned! This deserves so much more likes!
Hi Tim! I believe your calculator is in radian mode instead of degree mode, which will give you a different answer. To learn how to change the mode of a TI-84 Plus calculator, you can watch my 30 second video right here: th-cam.com/video/avUY53N_UWw/w-d-xo.html If you have a different type of calculator, you can search for a tutorial on how to change from radian mode to degree mode on your calculator. Hope this helps!
I know this video is 4 years old and I won't get any replies but how in the world did you get .90 from Sin(B) if we don't even know what B is in the first place?
You are really crazy to draw angles greater than 90 degrees i.e. obtuse angles as acute angles in your first two examples. The ambiguity of SSA can be solved quickly as follows: For angle A as an acute angle, (1) No solution when side S opposite to angle A is the shorter than the other side S x SinA. (2) Two solutions when side S opposite to angle A is longer than the other side S x SinA but shorter than the other side S. (3) One solution when A is a right angle or side S opposite to angle A is longer than the other side S. For angle A as obtuse angles, there is only one rule i.e. no solution for side S opposite angle A is the shorter side and one solution when side S opposite angle A is the longer side. Use 3 seconds to get S x SinA with your calculator when angle A is an acute angle and side S opposite angle A is the shorter side. Don't waste time calculating with sine law when no solution is possible. Calculate the supplementary angle only when two solutions are possible i.e. when angle A is an acute angle and side S opposite angle A is the shorter side but longer than the other side S x Sin A.
This was so confusing at first, but you made it so much easier ☺️
I’m so glad this helped!

You’re welcome! I’m so happy this helped!
I had to memorize the 6 Ambigious cases for a test and this just made it way easier than memorizing. Ur a lifesaver!

I needed this so much! You're the best!!
Oml thank you so much was so confusing initially , ty for the visual stuff , made it so much easier.
I don't know if this is harden than or easier than memorizing the rules, but it is still a really cool way to approach ambiguous cases of sine.
Really Improved Comprehension!
This is absolutely lovely! Thank you!
Amazing!
You reach a 100k for sure.
When I put the 155sin5.9/sin70 in my calculator it keeps giving me -74.88? What am I doing wrong?

Thank you!
I’m mind blown
🤯
very genius
Thanks!
So simple!

muy inteligente
Gracias!
thank you pookie bear
