It is this kind of videos that empowers alot ,that face prejudice and mockery among other learners for being slow and needing demonstration it is a place where one slowly work through to victory ♥️☺️ i am one of them

this is such a great video i dont get how this video has such low views it is one of the best qualities out there when it comes to maths topics

@1stClassMaths 4 ай бұрын

Thanks for such a nice comment! I am sure it might gain more views over time, the algorithm just doesn't like to pick them up apart from my quadratic sequences video that it loves! (Even though that's old and actually not very good!)

wow you actually need more recognition i've been looking for a video on the sine rule specifically and didn't understand any. I just pressed on any video I saw and i'm so glad i came across this channel you guys are so underrated. 🙏

Very kind of you although it is just me working on this on my own.

@@1stClassMaths if you dont mind me asking, on example 2 finding a missing side i put in the exact same thing on my calculator and i got 29.5847775 whereas you got 29.60732007. Am i doing something wrong?

@1stClassMaths 2 ай бұрын

@@user-ok2fj1pl5s Hi thanks for this. You are correct. When I make these animations I copy and paste text boxes. In this one I have copied the "0732007" from somewhere else and forgot to change it! I have added a note to the description. (The answer is still 29.6 obviously).

I don't have time to watch the whole video now but I will leave a comment to help other viewers of your video avoid potential confusion. What you call the "sine rule" is usually called the law of sines. There is a law of cosines and a law of tangents as well.

@1stClassMaths Ай бұрын

Hello from the United Kingdom where it is called "the sine rule". This video is designed for students studying GCSE maths and as such nobody will understand or use "the law of sines" I am afraid.

@learnOnline365 Ай бұрын

My first time also to hear the law of sine. We call it sine rule in igcse😅

Why is my answer different from yours 😭 please how do you type into the calculator🥺 to get ur answer coz mine is different

@1stClassMaths 17 күн бұрын

Your calculator probably needs resetting as it will be in radians or gradians rather than degrees.

12:13 "From the diagram given, X is an obtuse angle and the acute angle must be rejected." If no diagram is given, then both cases must be described.

@1stClassMaths 2 ай бұрын

I don't understand if this is a query or not? Exam questions will almost always avoid ambiguity. You also cannot an angle is obtuse because "it looks like it from the diagram".
