but the last 2 summons that doesn't happen

and man they totally simplified the plot from what it was going to be which also causes conflict with the movie.... dammit square you should of given them more time <.< but the game is good i'm just complaining about story stuff

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

thats how to solve it

what?

where does sin squared equal 1/2?

30?

so just route 30?

i have to actually do this out

do i just say

no

its not 30

then im confused

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

but how do you do it with sin2x?

hey mister math major @Phijkchu_Pikachu please help

k

ah

i thought you were the math major?

or are you the science major?

i'm engineering

ah

alright

what is the question

sin^2x=1/2

no calc

just don't tell him the answer

i need to do it out

It is just a double angle formula thing

shouldn't it be

ok look at sin^2 + cos^2 = 1

oh

sin squared

thats an easier way

yeah

sin squared

i can do sinx=1/2

the squared is throwing me off

sin^2 + cos^2 = 1 or unit circle both answer it easily

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

no arcsins will be used

yes

you don't need triangles

i know special triangles

im in precalc honors, we are on trig identities

sin^2 + cos^2 = 1

proofs, arcsine, etc

okay

i know that

so disregard leg

i dont see how that helps me

thank you

use the special traingles

thats the only equation you need

since sqrt(1/2) is the same as 1/sqrt2

thats how you do it with unit circle

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

alright

thank you

on friday we had this hell test
