For 25:13, you didn’t say the angle was obtuse so why do I have to take it away from 180?
best video iv watched for learning the sin rule, could not be anymore straightforward
innit
for the last answer, did you mean degrees?
Yes he obviously did - people make mistakes
I think he did. Answer in degrees
Brilliant video !
veryvery
29:00 it is degrees i believe not metres
charge it innit
where do you get the calculator online fromi cant seem to find it anywhere...
at first I got it but Im very confused now. some questions you do sinX.. and some you do X.. and some you do sin-1 so confusing....
only when it comes to working out angles you do sin-1
@@dynami9746 correct, use the inverse function of sin for ease of calculation of a missing angle.
charge it
How did you know the answer for the last question was an acute angle? Should you trust the diagram?
didnt say to scale so no
Wasnt the 2nd question supposed to be x=20.9064 not 8.45 I checked it every where
nah 15/sin(97) x sin(34) is what you're meant to put in the calculator and the complete answer is 8.450885169
Yh if you put that into Photomath it gives that answer, but you’re meant to put it in a scientific calculator
Im currently in yr11 my maths exams in abt 2-3weeks i couldnt do the sine rule until now
Thanks :)
i have my maths edexcel igcse today and ive been watching your videos maybe for 4 days now and im ok with maths now i used to get low marks even for my mocks lets see how it goesss ahhh idk
how did it go??
@@mya.tatum. i got a c sadly but i was about to fail according to my teachers so i feel like i did good
Is the longest side of the triangle always little a just like how the longest side of right angled triangle is the hypotenuse
