W for explaining it so well thank you so much❤❤

Thanks man i got exam in a month

When to use cosine rule as opposed to sine rule ?

Grazie prof.❤

Thank you 👍🏻

Thank you for explaining however I have one problem, when I type the exact same formula on the calculator, I get a whole different result and it's the same thing with all the other exercises I've done...

so USEFULL!!!!

Would this ever come up in a non calculator?

I like it too much😍

hey my teacher taught us cosine rule as a²= √b²+c²-2abcos a 1:06

FINAL MATHS EXAMMM🎉🎉🎉🎉🎉🎉

When I type both of the fractions at 5:44 and 7:00 into my calculator, it gives me totally different answers than to what's shown. Please could you offer some help as to why that could be because I am really stuck on that for the time being

does it matter if we put our answer in a different decimal place like 2 dp if they don't specify?

I wonder why is this formula is similar as this formula (b-c)^2 i think there might be some relationship There's just add cos(A) with -2bc This is suspicious

LIFE SAVOR THANBK YOU

paper 3 predicted paper should be the best one!!!
