Fairly sure question 6 is A.I'm hoping I got all 10 correct (aren't we all):
1)c
2)d
3)c
4)d
5)a
6)b
7)a
8)d
9)b
10)c
I think it is a...Fairly sure question 6 is A.
The general formula has a though, so when you divide by the 2 you just get6a was the general formula one right?
2x should = the general formula i think, so i figured x= (general formula) / 2
oh wow, just saw the sin-1(a) not a... LOL aw man how did i miss thatYep 6 would be A
general formula is just pi not 2pi for sin though. and its sin^-1(a) not just a, so sin^-1(a) represents 2x which when divided by 2 is equal to x, which works with the general formula where you have to have the angle at the end. I'm pretty sure it's A) now.The general formula has a though, so when you divide by the 2 you just get
Im back to thinking it's B) again.. LOLgeneral formula is just pi not 2pi for sin though. and its sin^-1(a) not just a, so sin^-1(a) represents 2x which when divided by 2 is equal to x, which works with the general formula where you have to have the angle at the end. I'm pretty sure it's A) now.
pls be b...Im back to thinking it's B) again.. LOL
sin(2x)=a so arcsin(a)=2x
but lets do it in general for sinx first. Sinx=sina so x=a
x=npi+(-1)^n*a
sub in x as 2x and a as arcsin(a)
2x=npi+(-1)^n*arcsin(a)
so x=(npi+(-1)^n*arcsin(a)) / 2 which is answer b)
