I am working on a project that requires the changing of the radius of a pipe then finding the pressure of this pipe. There are two chambers C1 and C2 the liquide with x density is pumped into C2 using a piston pump. The liqude in C2 drains back to C1 at a constant rate of a. The radius of the...

I haven't had precalc 2 yet, so I'm not too familiar with sin, cos, tan, but I need this for my physics class. So if you guys don't mind giving me the formulas of sin, cos, and tan.. for example: Sin angle A = width/length etc. If I have a right triangle with a hypotonuse of 7, and an angle...

Hi Everyone, I read the Tesla patent about bifilar pancake coils here: http://www.magnetricity.com/NeoG/Bifilar.php and I read about how they are supposed to decrease the impedance and increase the capacitance of the coil. So I constructed one to try out the idea. To my surprise, when I...

Hello..my question is from wilson theorem: (p-1)!=-1mod(p) how could you derive the formulae for pi(x) ?..this should be impossible as you can,t solve the congruence exactly a proposed method would be to find the roots of: f(x)=[\gamma(x)+1/x]-(\gamma(x)+1)/x that precisely x=p...

I'm reading Advanced Calculus by Wilfred Kaplan 1952. He is demonstrating how to find the decomposition of the acceleration vector into its normal and tangential components. I'm following along until he replaces the magnitude of the derivative of the angle with respect to the distance traveled...

I am working on a problem in which there are 100 widgets. I need to find how many samples of size 5 there are, which I found to be 75,287,520. No problem there. I am not sure how to go about the next part, however. In the original set of 100 widgets, 3 are broken. How many of the samples of...

I have often noticed something between distance formula: d(P_1,P_2)=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} and equation of a circle: (x-h)^2+(y-k)^2=r^2 There appears to be a relation between the two. It seems as though both h,k can be replaced with an x,y (in the eqaution of a circle...

ok, so my problem goes like this: I have that the integral of dx/((cx+a)(dx+b))=1/(ad-bc)lnabs((dx+b)/cx+a)) + C I have to use differentiation to verify the integration formulas. So far I've gotten to: D(1/(ad-bc)lnabs((dx+b)/cx+a)))=(1/ad-bc)((cx=a)/(dx+b)) => (cx+a)/((ad-bc)(dx+b))...

I know basic formulas / symbols in LaTeX, but I'm not too good with the whole PDF thing. I mean, once I have a .tex file I can make a PS, DVI, or PDF file no problem, but the .tex file is the hard part. Every tutorial I read is like 100 pages long. Does anyone have a brief tutorial that gives...

In the same way that it is possible to derive most trigonometric identities from the addition formulas, what is the way that the difference of sines and cosines formulas were derived, such as \sin{a}-\sin{b}=2\cos{\frac{a+b}{2}}\sin{\frac{a-b}{2}} thanks, I am trying to avoid as much...

[SOLVED] How to deduce rot and div formulas under spherical or cylinderical coordinat It is said that in general, these formulas are: if dl_1=h_1du_1, dl_2=h_2du_2, dl_3=h_3du_3 then \nabla \Psi=\frac{1}{h_1}\frac{\partial\Psi}{\partial u_1}\vec{e}_1 +...

While working through a problem I arrived at a stage where a vector, say V being parallel to the plane I'm trying to find the formula for. Taking the normal vector of the plane to be n I used the dot product: n*V=0 in this case I knew V to be <-2, -2, -1> and n I set to <a,b,c>. This leads...
