I love you so much. Our math department literally just assigns TAs (teaching assistants) who don't teach for our precalculus class and it's terrible. I don't like teaching myself but you make everything understandable
I watched this because it's been a REALLY long time since I've worked with these situations and needed to refresh my memory. Thanks for the resource! It was really helpful. However, I noticed that at 0:57 you say "perpendicular bisector", which is probably why, in another video on the same topic, one of your students suggests that you could simply divide the 12.75 by two. Just sayin'. Thanks again!!
EVERY teacher makes mistakes at times (they’re human too lol). Thank you for being such an amazing teacher to all of your internet students like me lol!
you are very welcome! I think it is easy for me to hide my mistakes and take down the videos. However I want to own them so you learn from them and know even after doing the problems 1000 times I still will make mistakes
this helped me a lot. Your the only teacher that I can really understand how I can use the law of sine and the law of cosine,, thank u very much great brian McLogan..
Was struggling in this topic but dyer watching your video it all make sense now. Thank you for explaining every step and taking time to go over everything. This video helped me a lot!!
In triangle (A,B,C) (sides (a,b,c)) The problem c-A-b has always one solution regardless of values of c, A and b. The problem A-b-a has (1) one solution one A≥90 and when a>b, (2) has no solution when A≥90 and when a≤b, (3) has no solution when A
I noticed around 4:41, when you move on to the second triangle that the first one is wrong. Shouldn't the equation be 15sin40? b=15 and A=40 since the equation is h=bsinA. Just bringing it to your attention
Constructive criticism: I think you should've just started your video over after messing up a coupe of times. Lead to me being confused and not knowing what was right and what was wrong. Hopefully this will help you out for future videos. Thank you for helping me prep for my Trig final! :D
I have a question. In a problem I have they give me b=500, c=330, and gamma=38deg and asks if there are none, one, or two triangles. When I finished solving for one triangle I began to check for two triangles. However, side a was not less than side b so I stopped there and said there was only one triangle. I got the dimensions for the first triangle correct but it says that there are actually two triangles. So my question is, can you say that if ch? Thanks!
@@marcus3435 in the ambiugous case there are two possible values for angle B. its either the value you get or 180 minus that. If B prime worked that time and the angles didnt exceed 180 it would be our second answer. here it didnt work do we realized there was only one triangle.

when I get rich, I will pay you back for the amount of free tutoring you gave to this world.
cheers! happy to spread my knowledge and experience

ok lol
I forgot this and I have a test in a couple hours. I think you just saved me. Tysm!

Thanks for keeping this video up! Saving my final grade! Forgot how to do this or wasn't taught, can't recall! Appreciate.
Wait, actually on the first problem, why is it 40sin(15)° and not 15sin(40)° if the formula is bsinA?
m∠A = 40° a = 20
m∠B = b = 15
m∠C = c =

Thanks for addi g
I always find myself coming back to your videos so I think its time I subscribe (:
Haha yes!
Excellent video and method for an often overly complicated topic.
Thank youuuu, always saved right before the test
Thats a mood
Great video! Keep it up, you're helping a lot of students out there :)
Thanks for the help! Very clear and easy to understand! You are my go to teacher on youtube whenever I need help in math.
Brian I have been using your videos all semester. Thank you for putting these up!!
you are very welcome! Happy to help!

yes that is correct, as I work through the problem I correct the mistake, thanks for bringing it up though

I totally agree with you and I apologize. Thank you for bringing that to my attention as it is good to note for other problems
You have saved me thank you 🙏🏼🙏🏼
Very helpful video! You are like my second math teacher and I really appreciate it.
Happy to be there for you Salem!
Thanks :) also realized I spelled helpful wrong.... haha
Very Helpful. It's like being in class but at home😃
yes!!
Brian McLogan Legend! you still reply to comments in a video from 2 years ago!
Brian McLogan Just wanna say, my teacher taught me this but I was so confused until I saw your video. Gonna help on the final thanks man!
Thanks again. I actually understood the concept.
I have a question. In a problem I have they give me b=500, c=330, and gamma=38deg and asks if there are none, one, or two triangles. When I finished solving for one triangle I began to check for two triangles. However, side a was not less than side b so I stopped there and said there was only one triangle. I got the dimensions for the first triangle correct but it says that there are actually two triangles. So my question is, can you say that if ch?
Thanks!
so I do not have time to work out individual problems for students as I have multiple requests
Free Math Videos Oh I don't need the problem worked out. I just want to know if it is correct to say that if ch?
I am teaching this stuff soon, in the mean time ruclips.net/video/cmBz38GWu78/видео.html
To answer your question, there is a way to see if the third side length can make two triangles.
lmaoo the confusion on the first problem #RELATABLE
Thank you so much! It makes much more sense now.
Just got it, now it makes sense
Tks Brian McLogan. This is a great help
you are very welcome!
Thanks, helped a lot in understanding this for my test!
great! how did you do?
Thank you, sir! I appreciate your way of teaching! Keep it up.
you are very welcome! happy to be able to help
Great video ! It really helped me understand 👍🏻👍🏻
awesome! happy to help
Thank you!!!! Great teacher and thoroughly understood the content :-) much appreciated keep up the great work
appreciate it and very happy to be able to help you out!
thanks
Thanks for this video! I’ve had two different teachers explain this and didn’t fully understand until your video.
it is a confusing concept for sure, happy to be able to help
King of math
Just happy to help
you have h=bsinA with b=15 and A=40 so... instead of 40sin(15)=10.35. You want 15Sin(40)=9.64
thanks..i got what you mean..its really help me..
awesome! happy to help
Thank you so much sir!
This sir is a legend
just happy to be able to help
what was the B prime for?
that sigh at the end; haha

thx
Thank you so much for this!!!!
you are very welcome!
Thank you for your videos!
you are very welcome!
Well done
thanks Eileen!
Thank you!!!!!!
Mistake: for one triangle a and b can also be equal. But u said a>b
need this because my teacher couldn't really.... teach. thank you
you are very welcome!
Great video! just focus on not making simple mistakes next time.
yes sorry about that
God Blessssss! This helped me so much! Thank you!
you are very welcome!
You should start all over again, and make sure you have correct numbers, units, etc.
where did I go wrong?
Thank you
you are very welcome!
THUMBS UP!!
Hallelujah
bit messy but some great teaching.
my work or explanation?
Very messy and confusing. Should find a different job.
I was fired for being messy and confusing 🤦♂️
