and i had no idea how to do it

and we have 10 minutes to finish on monday cause nobody came even close

on friday we had this hell test

thank you

alright

so pi/4 +2piN, 3pi/4 + 2piN

which is pi/4 i think

so its arcsine of 1/sqrt2

thank you

i dont see how that helps me

i know that

proofs, arcsine, etc

im in precalc honors, we are on trig identities

i know special triangles

yes

cause normally i would just take the square route, but i dont know how to do arcsin of sqrt(1/2)

the squared is throwing me off

i can do sinx=1/2

sin squared

yeah

i need to do it out

no calc

sin^2x=1/2

alright

ah

or are you the science major?

i thought you were the math major?

ah

but how do you do it with sin2x?

i know sinx=1/2 is pi/6 +2piN, 5pi/6 + 2piN

then im confused

do i just say

i have to actually do this out

so just route 30?

30?

what?

im asking how to solve

i know that

thats not helping me

or anyone?

i cant use a calc

what is sin squared x = 1/2?

like, badly

i need help

@legorhin arent you really good with math?

you guys know math right?

WAIT

should i name my bot robot moron?

question
