Ok, so I figured it out. It's: y^2=12x+12 y^2=12(x+1) x=-1 So y= 0 I don't know why that took me so long. Math brain. Thanks.

Homework Statement I'm trying to find the vertex of this parabola: y^2-12=12x The Attempt at a Solution Initially I tried to take the derivative and find the vertex by finding where it the function is zero, but apparently that does not work in this situation. Is it because it is not in...

Ok, I think I've got it. It does not exist, since the sequence oscillates between 5, 4, and 3. Thanks!

Oh, so because it oscillates between -1 and 1, then the limit is from 3 to 5?

Would the limit be 5 since sin(pi\2) is 1?

Homework Statement I'm trying to find out whether or not this sequence diverges or converges. If it converges, then what's the limit. {4+sin(1/2*pi*n)} The Attempt at a Solution This one is a bit confusing to me since sin oscillates between 1 and -1. So if you plug in (pi*infinity)/2, that...

It makes sense now. Thank you so much!

Homework Statement The force exerted on a certain object varies with the object's position according to the function Fx(x)=ax^2+bx^3 where a = 3 N/m^2 and b = -0.50 N/m^3 . What is the work done on the object by this force as the object moves from x=−0.40 m to x = 2.0 m?Homework Equations...

Ok, that makes sense. Thanks!

Two 2.4-kg blocks are connected by a string draped over the edge of a slippery table, so that one block is on the table and the other is just hanging off the edge. A restraint holds the block on the table in place, and the string is 0.50 m long. After the restraint is removed, what speed does...
