<b>I need a brain refresher</b> to see if i have everything straight in quintic and quadratic expressions.
The n's in an expression represents how many turns a line would have
The amount of (x+1)^2 means a quadratic curve
The if the n is odd there are no complex roots
Now here is the...

Remember its a parabola connect the dots.
This is what i have done
x^2/a^2 - y^2/b^2 = 1
then i substituted a as 0 and b as 16 and it got me nowhere
I'm guessing it has to be located at 0 but i...
I'm trying to put this into factored form help me out and help me with ellipses I don't know what to do... Would i have to place the C that i solved into a^2 = 10^2 + 25.4^2 http://s65.photobucket.com/albums/h237/runicrice/?action=view¤t=scan.jpg
Okay can anyone tell me why is this true for restriction of 0 < x < 360
sin(x)=0.15, x = 8.6 and 171.4
cos(x)=-.655 x = 130 and 230
tan(x)=0.75, x = 36.9 and 216.9
I don't see a pattern or rule...
please co-ordinate me through the use of graphs if you can my teacher didn't explain it well.
this is my question:
A Building sways 55cm to the right from origin in 5 seconds and 55 cm to the left of the origin in 35 seconds. And i am supposed to write an eqaution to define this.
I'm guessing the is no amplitude no vertical translation and since it's sine basically I am going to...
My davey jones's locker i think I've got It!
Correct me if I'm right
0=(x-(2x))(x-(-2x))
0=(x-2i)(x+2i)
0=(x^2+2ix-2ix-4i)
0=(x^2+4)
am i correct?
now if the pairs were 1+3i, 1-3i I would have sub the same way like
0=(x-(1+3i))(x-(1-3i))
0=(x-1+3i)(x+1-3i)
and solve from that correct?
I doubt that hootenay... I'm thinking of x = -b -+ Square root of b^2-4ac over 2a equation and deriving it so that something will occur... I am confused...
Hi, I'm not sure if this is calculas based or algebra based so here's the question.

(A) 2i, -2i
For this question i don't know what is being asked so i guess the pairs could be x...
I know this:
ax^2+bx+c, a(x-h)^2+k and a(x-s)(x-t)
So the problem is how can i use the things that i...
