The Ambiguous Case for Sine Law - Nerdstudy

thank you very much

This is a brilliant video.

I love this video, but love her even more😍

thanks

saved me. the stupid book we use at school cant teach!!!

this math vid is precise

this is so well explained! now I finally understand it

omg i understood this so quickly. tysm i have a test the day after tomorrow and i had like 5% idea of this and i feel like my math teacher just overcomplicates this.

She’s hot too all around great video🎉

I have a test on this at 9 AM, watched this at 8 AM. Now i understand this. Thank you for helping me not fail

Holy shit, I did not understand this concept at all but thank you know I understand it perfectly.

This is much easier to understand. Thank you so much. 💛

great video! thank you for getting me through trig assignments

Thank you so much this makes much more sense then when my teacher taught me it!

I was really confused about this, so I decided to watch a video explaining about this.
Amazing job! Y'all explained this nicely and clearly.
Thanks a lot! Really helped me out a lot!! 👏 👏 🔥

THANK YOU

My test is in one hour.. you just saved my life😭

To have a complete explanation, you have to include "a" longer than "b" and angle "A" being obtuse. An algebraic explanation to supplement this geometric explanation is that sin function can only be equal or smaller than 1 leading to no angle solution when it is greater than 1 (when "a" smaller than b sinA), and a positive sine function gives two solutions of angle value, an acute angle in quadrant I and an obtuse angle in quadrant II leading to 2 ambiguous solutions (The obtuse angle solution is eliminated when "a" is longer than "b" as the angle is an exterior angle of a triangle formed with opposite extension of the third side, resulting in one unique non-ambiguous angle solution. SSA is a valid congruence test when S opposite to A is the longer side!)

Try Trisolve

Which software do you use to animate?

This is by far the best explanation I have come across yet. Thank you.

It's been 6 years but your explaination is still better then others

What an amazing video

Easily the best explanation I have seen - thank you. One question though. I thought the second example would show a case where the final check would show angle A + angle B >= 180. Instead, it was just like the first example. Is that final check necessary? Are there cases where the angle A + angle B equals 180 degrees or more?

👍

I show my students this every year. The animations for the two triangles show a superb explanation

This works pretty well! thank you, but how does it apply to questions where i only get 1 side and 1 angle, as usually thats what my test gives me

Okay this was the best explanation I've ever seen for this. Teachers make it so confusing

I can't believe I had such a hard time understanding what was happening. This was so clear and concise. Thank you.

Wonderful . Thank you for making 'the ambiguous case' easier .

Your way of teaching is so good that this 7 minute video explained a concept I've been struggleing to understand for many months. Your visuals are so easy and so straightforward. Thank you! ❤️

What of the triangle is not drawn to scale?

Smash

bless ur heart!!

baddie

Bro this video actually helps so much I had no clue what to do before watching and now I understand it all

This was very helpful thank you. I noticed that you didn't solve for the bottom sides of the triangles for the examples.

I worked out the sides for the first example getting 4.8 for the left and 3.4 for the right.

Can anyone confirm whether or not this is correct?

Saved my life

Good work

this video has actually just saved me, this has been so confusing and im so happy to finally understand it!!!!

Thank you so much, I’ve been struggling for weeks with this concept. My teacher is so bad at explaining (or js too fast). Thank uuuuu!!!

Great video. It’s also true that 109.9 has a reference angle of 70.1 if you want to keep the students thinking in those terms. Sin B is positive in both cases. I know I’m teaching this lesson right after teaching evaluating using inverses which can also create ambiguous situations. Just an idea.

awesome!

Very well done, I've never understood that chart they give in trig books with the cases, but now I do for the first time. Thank you so much!

What if I don’t have the length for the two hypotenuses.........??

Very helpful!!

I have a test tmr and this helped me so much. Thank you!!!
