1. Programs Chemistry major looking for a way out.

Excuse the tangent, Which University do you attend, if I may ask? As I am also Australian, and have a friend who had pretty much the same crisis.
2. Complex Numbers: Equation involving the argument operator.

Cool beans, Is there a simple way to solve these though? A shortcut method? Wait, I found it... It's the line created from the points z1= -1-2i and z2 = 2+3i Gradient = \frac{3 - (-2)}{2 - (-1)} = \frac{5}{3} y = \frac{5}{3}x + b (-2) = \frac{5}{3}(-1) + b -6 = -5 + 3b -1 = 3b b =...
3. Complex Numbers: Equation involving the argument operator.

Homework Statement Question: Homework Equations Any relevant to complex numbers. The Attempt at a Solution Given, Arg(\frac{z}{w})= Arg(z)-Arg(w) z=x+yi z1 = -1-2i z2 = 2+3i Arg(z-z1)=Arg(z2-z1) LHS: Arg(x+yi+1+2i) Arg((x+1) + i(y+2)) tan(\theta)=\frac{y+2}{x+1}...
4. Wave paddle application Integration problem

What do the values 'p', 'g' and 'w' represent? If they are just constants, then remove them from the integrand. Eg.
5. Work done on a block

If you lift an object, you are giving it gravitational potential energy. So, to put it at the top of that incline, it will have gained potential energy. When it is released, it is losing potential energy, but gaining gravitational kinetic energy. KE = PE ================== When...
6. 3dimensional wave propogation.

Actually, that would be interesting.. Thank you for the assistance though. ^_^
7. 3dimensional wave propogation.

Essentially, the function for this: There isn't really a context, I'm not currently studying anything relating to this, it just interests me to see the behaviour of waves. I seem to have found it, by looking for an example image. z = sinx(√(x2+y2))
8. 3dimensional wave propogation.

I thought the maths area would be the best place to ask.. What kind of function would represent a 3 dimensional sine wave? A sine wave, where the z-axis lays on the circumference of a circle.
9. Resonance in a Wineglass

The length will affect it more than anything; the standing wave that occupies it is determined in large by the length, as this affects the number of nodes that can form.. f=\frac{nv}{4L} n = harmonic [where you can only have odd harmonics [1, 3, 5, etc].] L = length. v = velocity of the wave.
10. Momentum Theory question Gr.12

(ms×vs)+(mb×vb) = (ms+mb)v^2 Where: ms = Mass of student vs = Velocity of student mb = Mass of bag vb = Velocity of bag In writing; The sum of the initial momentum (p=mv) on both objects is equal to the final momentum, where the masses are combined. If you have objects moving on angles, you...

In which way? I could make V= 55L2H {Area of the base × height.} I haven't tried using my premise that the most efficient {volume:surface area} is a cube, with the implication of V= L3 I'll give that a shot. Otherwise, I am truly stumped.
