ok so i was presented with the equation x^2-7x+12=0 and i can't decide what the answer should be. if i factor the equation i come up with 3 and 4. but when i plug those back into the original equation it doesn't work. so does that mean that there is no answer or does it mean I'm doing...
i'm kind of new to this website and i was just wondering if anyone could tell me if my math is wrong here.
for the purposes of this thread sqrt means square root
my logic for 1+1=0 is this:
1+1=1+1
1+sqrt(1)=1+1
1+sqrt(-1*-1)=1+1
1+sqrt(-1)*sqrt(-1)=1+1
1+i*i=1+1...

first off yes i am trying to conceal my real plan because i believe if i give out to much information someone will beat me to getting it built and i don't want that.

i'm not sure if this is going to work but I'm trying to attach a crude picture i made of what it will look similar to.
the picture is basically a base (which I'm thinking about using pvc pipe or wood for) two holes on either side to hold the rod in the middle that will be spinning and the...
i'm doing a science experiment where i am trying to direct electric current very precisely. in the experiment there is going to be one piece spinning very fast. now if the electricity wasn't an issue i would use copper for the frame and have it spin on that. but copper conducts electricity so...
what it seems like to me after reading everything that is on this one is that your friend isn't acknowledging that there are magnetic fields around the magnets instead of just pulling forces of the magnets. when the magnets are close enough to really affect each other the magnetic fields are...
