Anyone know where I could find a couple of chemical equations for Thorium. I need them for a project I am currently doing. I have not been able to find any.:uhh:
Thank you.:smile:
Well, I got this equation f(x)=\frac{2\sin{2x}}{x} [-\pi,\pi]
So I took the 1st derivative, f'(x)=\frac{2(2x\cos{2x} - \sin{2x})}{x^2}
Then I set that equal to 0, and got 0=2x\cos{2x} - \sin{2x}
But I do not see how to get the critical numbers, I also tried to do double angle, but that...

This somehow seems easy, but I cannot get the jist of it.
f(x) = x^3 - x^2 - 4x + 4
The point (a,b) is on the graph of f and the line tangent to the graph at (a,b) passes through the point (0,-8) which is not on the graph of f. Find the values of a and b.
okay so, ive spent about an...
I didnt go to school today, and so missed day of class, now i all lost someone help.
White light is incident normal to the surface of the film as shown below. It is observed that at a point where the light is incident on the film, light reflected from the surface appears green (lamda = 525...
While exploring a sunken ocean liner, the principal researcher found hte absolute pressure on the robot observatino submarine at the level of the ship to be about 413 atmospheres. The density of seawater is 1025-kg/m^3.
Calculate the gauge pressure p_g on the sunken ocean liner...
This is not exatly homework, but it seems the best place to post it.
Let A, M, and C be digits with:
(100A+10M+C)(A+M+C) = 2005
A. 1 B. 2 C. 3 D. 4 E. 5
maybe some one can help me out on this, was one of the test questions i did not know how to do. :blushing:
Took it today, whew that was tough, anyone know where i can get some practice on the problems, i would like to do alot better next time around. :P
Or you can post what u though of the test. Personally i though it was tough, saddly i only awnsered 9 of them :eek: . Also if im not suposed to...
Okay, i found this problem to be pretty tough, maybe someone can lend me a hand.
Theres a container with a piston, and theres a gas on the bottom of the piston.
State 1
A=1.2 x 10^{-2}m^{2}
T_1=0^{\circ{}}C
V_1=1.5 x 10^{-3}m^{3}
P_1=1.02 x 10^{5}Pa
State 2
Theres a 150kg weight...
In an experiment, .02 kg of substance is heated in a bath of boiling water until its temperature is apporoximately 100*C. The substance is the placed in an insulated container that is holding .10 kg of water at 25*C. The final equilibrium temperature of the mixture is 32*C. The specific heat of...
Can someone help me, I put

I even tried to do this with .eps, but it still keeps saying that its an undefined control sequence.
i couldnt find a place to post this question but this seems to work, so is there a way to make latex outside this forum, like if want to do a project?
if so how.
I got this problem for physics and i cant seem to get it, it goes like:
A projectile is launched at an angel of 40 degrees with an initial velocity of 100 m/s. One hundred meters away is the beginning of a hill that slopes upward at an angle of 20 degrees. The projectile strikes the hill a...
srry to be a bother but can someone help me on how to do this, it explains it in the book but i dont understand.
Here it is:
arcsin(sin 3(pi))
i would really appreciate ur help, and thxs before hand. :smile:
