thank you so very much,even after 10 years you're a lifesaver. I was able to get a 62% on my test and passed so now i dont have to redo the course in the summer, appreciate it.
I'm in grade 10, u saved me from this, I was away for a while and didn't understand anything about this, I got an 80% on my test because I watched this until I got it, thanks, thanks and thanks again
Hey Ben, thanks for the comment. I really appreciate hearing from people that find my videos help them understand some math. You sound like someone who has figured out how they learn best. Good on you for the effort you put into this and the success you have achieved. Take care, Al.
This is so helpful!! Thank you so much, I’m starting my math mock exam in an hour and I managed to understand the law of sine and cosine properly because of this video
Very definitive, clear and easy to understand. I was having a lot of trouble figuring out when to apply each rule, now iv'e got it sorted. Absolutely ripping! Thanks!
This was so helpful. I'm in a unique position where I'm teaching a student geometry, and geometry is NOT my subject. We've managed to get through things right up until the curriculum combined Law of Sines and Law of Cosines. What the curriculum failed to make clear was that which law you use can be fluid and that there are multiple ways to arrive at the same solution when you're trying to find multiple variables (I was given an answer key which showed one way to solve a problem). As a result, I was stuck puzzling over why one law was chosen over another in certain circumstances. The Angle-Side Pair idea and the idea of using cosine between two angles was enormously helpful. Above all though, when you used BOTH Law of Sines AND Law of Cosines to find the SAME missing variable was like opening my trigonometric third-eye. Law of Sines and/OR law of Cosines. Depending on the circumstances there are instances in which either law can be used to find one variable. It sounds so simple now, but this blew my mind. Thank you for explaining this in such a way that it knocked me out of my rigidity. Both I and my student will undoubtedly benefit.
Hi Zachary, thanks for sharing. I enjoy hearing from people that find my videos helpful. One of the beauties' of trigonometry, is once you start finding more sides and angles you get additional ways to deduce other sides & angles. Cheers.
Mr.AlRichards314 i was clueless on how to do trigonometry until i saw this video, i want to thank you from the bottom of my heart for helping understand what my teacher made seem like rocket science, i will proudly suit up and take my unit test tomorrow, thank you sir
Hey. Check out this video of mine at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n_iJ5ffy1Jk.html that shows how t find an angle when you know 2 sides. It also shows how to use the Sine law to verify that calculation. Hope this helps.
You are correct. I didn't show that angle B could also be 107 degrees because my emphasis was on how to know whether you should use the Sine of Cosine Law, not the SSA ambiguity.
OMGGGG I CAN NOT THANK YOU ENOUGHH FOR THIS VIDEO I WOULD BE SCREWED FOR MY MATH TEST TOM. IF I DID NOT FIND THIS VIDEO!! Believe me I watched over 100 videos since 9 o clock and it's 12:08 and your video out of all the other videos happened to be like the holy grail!! And now I won't fail my math test tom!!!! Haha!!!! And I was absent for like 2 days and just being absent from math for 1 day every student knows this your technically screwed. So I wanted to say thankkk youu so much once again!! And l do not have a math brain what so ever and this totally helped me! And I got sooo excited when I figured it out because of this video i sent it to all my friends in my grade 11 math class because no one like gets it.
The tutorial was created in PowerPoint. I drew all the diagrams using the drawing tools in PowerPoint. The equations were made with MathType within PowerPoint and then recorded using a screen capture app called Camtasia.
Wow I was scrolling through the comments and all I thought to myself was “these comments are all good except the video is going to be just like any other,”but I was completely wrong. Thanks for the help
@@Lukas-cz5ee Yes, I do. Many of my videos are organized here: sites.google.com/view/making-sense-of-math/home Under Trigonometry, go to Graphs of trigonometric Functions and you will find several different ones. Enjoy.
That would be a proof that the Sine Law is correct, but that wasn`t the point of this tutorial. The focus of this video was to show under what circumstances you would use either law.
