1. ### Basic Factor Question

OMG, Thanks for the help. I just could not see it and now it is as plain as day. I do that a lot with math, Ijust get stuck in one path and can't figure it out. Thx for the help and have a great weekend.
2. ### Basic Factor Question

Hello all, I am stuck and need assistance. I need to know how my solutions manual goes from this (x-5)+(x^2(x-5)) to this (x^2+1)(x-5) ? Thanks for all the help. Naicidrac
3. ### Difference Between Inverse & Reciprocal

Ok awesome, Thanks for the clarity. I am thinking in terms of a trigonometric function like the difference between 1/sin(X) and sin^-1(X). What is the difference between these?
4. ### Difference Between Inverse & Reciprocal

Hello, can someone tell me the difference between reciprocal and the inverse. I have looked up the defenition and when I think I get a deep understanding I get confused. Thanks for all the help. Naicidrac

Darn, I put that it would be heavier in alcohol. Wait stop the press...Please forgive me, but I am just trying to get a deep understanding. I just found that the specific gravity of Alcohol, ethyl (ethanol) is 0.787, and the sg of Oil, Castor is 0.959. Now my test question just said...

Ok so if the alcohol was more dense then it would give more upward force and the answer is the ball would weigh more in the oil than in the alcohol?

Ok these are freaking awesome answers and they are getting to the root of the question. Now I am trying to understand this. So the displacement gives negative weight to the ball. So now if there were no numbers or calulations on the question would the oil displace more volume than the...

Ok so I checked out the link. this is me thinking out loud and writing it down. I know that weight is w=mg. I also know that the mass and gravitational constant would not change. The density of the fluid being displaced would be different. So I am still unsure. I guess that the oil is...

Ok I knew I would not explain it right. The ball is held down in the fluid by a string, that sting is attached to a scale so the weight of the ball can be measured. So you are weighing the ball as it is suspended into the alcohol and then again in the oil. I wanted to know if there would be a...

Hello all, I have a very basic question about fluids. Here it is. There are two containers, one has alcohol in it and the other has oil. A steel ball is held down inside of each. A scale will weigh the steel ball as it is held down in the alcohol and then in the oil. Will the ball be...
11. ### Need a little help please.

Yes, thank you guys for all the help. Now I see that as you are close to -2, |x| is defined as -x so the problem looks something like this. lim ((x+1)(x+2))/(2-|x|) x->-2 since we said |x| is -x we get 2-(-x) which cancels with the numerator and we are left with (x+1) and...
12. ### Need a little help please.

I have thought of it as a piecewise function, but my instructions are to solve this algebraically. I have also factored it ((x+1)(x+2))/(2-|x|). Now what? Thanks for the help.
13. ### Need a little help please.

I edited my post and Vegeta was correct.
14. ### Need a little help please.

Hello everybody. I just need a little help with some very basic Calculus. Actually I need help with the Algebra part, but it is a Calculus problem. Here is the problem. Lim x->-2 of (x^2+3x+2)/(2-|x|) That is it and I know the answer is -1, but I cannot get that |x| out of the...
