WAIT
you guys know math right?
@legorhin arent you really good with math?
i need help
like, badly
what is sin squared x = 1/2?
i cant use a calc
or anyone?
thats not helping me
i know that
im asking how to solve
what?
30?
so just route 30?
i have to actually do this out
do i just say
then im confused
i know sinx=1/2 is pi/6 +2piN, 5pi/6 + 2piN
but how do you do it with sin2x?
ah
i thought you were the math major?
or are you the science major?
ah
alright
what is the question
sin^2x=1/2
no calc
Also I am tech a science major leg
i need to do it out
It is just a double angle formula thing
shouldn't it be
oh
sin squared
yeah
sin squared
i can do sinx=1/2
the squared is throwing me off
cause normally i would just take the square route, but i dont know how to do arcsin of sqrt(1/2)
do you know the special traingles
yes
i know special triangles
im in precalc honors, we are on trig identities
proofs, arcsine, etc
okay
i know that
so disregard leg
i dont see how that helps me
thank you
use the special traingles
since sqrt(1/2) is the same as 1/sqrt2
so its arcsine of 1/sqrt2
yes
which is in one of the sspecial triangles
which is pi/4 i think
yes
so pi/4 +2piN, 3pi/4 + 2piN
