    y = 0, y = 3, x + y = 0, x + y = 2, 2x + y +3 z = 0 and 2x + y +3 z = 4.
    The entire thing is a contradiction.

    I dunno but x + y doesn't work in her equation.

    LOL @ Marwa Rolling Eyes

    He just mentioned integrals and Reimann sums and you guys are denying its calc? Rolling Eyes

    anyway I never took calc 3/multivariable calc ... this kid is either a genius to be placed in a class that advanced or he's just trolling ... I don't even know any high schools that offer calc 3 ... calc BC is the highest ive heard of at the HS level and thats up to calc 2 ...

    He's not in a class! He is in freaking 8th grade. He wants to "study on his own" Rolling Eyes

    My HS offers Mlti-Variable Cal...just 1 class though. (30 kids) from all seniors take it.

    He DOESN'T KNOW ANYTHING. HE IS A NOOB WHO WANTS TO SOUND SMART. TRUST ME. He doesn't know basic cal.

    wow , u guys call me a noob and troll for my curiosity ?
    and Ahmed i can do basic calculus. this was for my
    research class. And "Lady Emms" work might be correct.
    but i am pretty sure this is calculus.

    also Ahmed, you say I try to sound smart and everything
    and study ahead. I do study ahead. So what?? Is there a
    problem with that? Also you say i try to sound smart.I study ahead
    and i learn from that. You say "He DOESN'T KNOW ANYTHING.
    HE IS A NOOB WHO WANTS TO SOUND SMART". Thats
    why I can easily pass the Integrated algebra regents,know
    geometrical proofs, solve trig problems and graph them.

    you also said, "Yo Redwan, if you need help come to my website.
    I'll help you there." Now i ask for help and yea.

    This isn't curiosity. This is stupidity. You are nowhere near Cal. You still need Algebra, geo, then trig.

    What basic calculus could you do Redwan?

    LMAO! Study ahead by 2-3 years?? wth?

    That doesn't prove anything. Algebra is mad easy...most people at tech don't even take it...they start with Geo.

    Geo isn't all about proofs. Know all the theorems?

    You know very basic trig...sin,cos,tan right?

    no, it is curiosity. started with basic then went advanced.
    yea i know theorems. Pythagorean theorem, ptolemy's theorem theorem, Casey's theorem
    and some other stuff. i don't remember. For trig, i noe all the other functions like
    secant, and arcos. i can graph trig functions based on the period and amplitude, even
    if it shifts. I proved many trigonometric identities. tried basic calculus i.e limits.

    I don't mean those theorems. I mean theorems that you use to prove proofs.

    You do limits in only the first day of cal class...honest. That's not even considered basic...

    okay screw calc. This is actual hw.
    tell me if what i did is correct.

    question: given identity: sin^2(x)+cos^2(x)=1, solve for x in "3*sin^2(x) = 1+ cos(x)"
    change identity to sin^2(x)= 1- cos^2(x)

    3*sin^2(x) = 1+ cos(x)
    3(cos^2(x)) = 1+ cos(x)
    3- 3* cos^2(x) = 1+ cos(x)
    3cos^2(x) + cos (x) -2 = 0
    (3cos(x)-2)(cos(x)+1)=0
    If d= cos(x) then (3d-2)(d+1)=0 d=-1, 2/3
    cos(x)= -1, 2/3

    cos (x)= -1
    arccos(-1)=x

    cos(x)= 2/3
    arccos(2/3)= x



    thnx.
