Sine & Cosine Rules, Area of a Triangle [IB Math AI SL/HL]

[@nikitavrban2153]

It would be very helpfull if there were solutions to these examples as a way of checking it!

8:30 its 45* :)

[@nikitavrban2153]

And whats the angle?

[@david.nik21]

the second sine rule result is undefined. doesnt work. nsolve cant do it either

[@nonimaranga4729]

I've also just tried and it hasn't worked, its possibly because he didn't pick the values from an actual question but from the top of his head

hi, great vid, very helpful. I have a quick question for you tho:
for your second example on the sine rule (solving for angles) my calculator comes up with no solution, is this supposed to happen?

[@danbleil8299]

don't know if this will still help but i have the same problem so it's probably a mistake.

[@Tribune_of_Italia]

Side side angle triangles can have 0, 1, or 2 solutions. The 40cm side cannot "connect" with the unknown side stemming from the 60 degree angle, it's simply too short. Therefore, the "triangle" has no solution.

[@nikitavrban2153]

I'm still confused what??

[@goodluckmati]

@@nikitavrban2153 i worked with photomath and the solution for that simply doesn't exist lol, as I understand, he just made up silly numbers

[@ritwikagarwal6397]

really helpful

[@chobhamu1689]

Hi also for your second example with the cosine rule is there multiple solutions?

I need past paper practice with this lesson
