Math formulas needed.
I'm going to code a calculator program in QuickBasic, and I want to include sections for geometry, algebra (stupid quadratic formula ) and electronics. Could you give me a hand by posting the formulas for voltage, amperage, current, etc...? I'll post the app on my site when I'm done.

a = acceleration (m/s²)
g = gravitational constant (m/s²)
F = force (N = kg m/s²)
Ek = kinetic energy (J = kg m²/s²)
Ep = potential energy (J = kg m²/s²)
m = mass (kg)
p = momentum (kg m/s)
s = position (m)
R = radius (m)
t = time (s)
v = velocity (m/s)
v0 = velocity at time t=0
W = work (J = kg m²/s²)
τ = torque (J = N m) (torque is work in a rotational sense)
s(t) = position at time t
s0 = position at time t=0
runit = unit vector pointing from the origin in polar coordinates
θunit = unit vector pointing in the direction of increasing values of theta in polor coordinates

There are much worse equations than the quadratic.

Oh, crap... 
It's not that I find it hard, but it's tedious to do over and over again. That's why I wrote a QB program to calculate ax(squared) + bx + c. Just give it the values and it gives you the answer to the equation.

Yeah i wrote a program on my TI-84 to solve it.

the best way to remember the quadratic formula is to sing it
To the tune of "Pop goes the weasel"
x equals negative b
plus and minus the square root
of b squared minus 4ac
all over 2a
altogether now!
