How would one show a morphism is an epimorphism iff it is surjective (ONTO)?

I accidentally submitted thread before completion please disregard for now -fixed

I am trying to understand the quantum algorithm for order finding, but I can't find the proof anywhere. Can anyone help? Thanks in advance \frac{1}{√r} Ʃ^{r-1}_{s=0} e^{2πisk/r} |μ_{s}> = |x^{k} mod N>

How do you take the log of a 2x2 matrix in general where all entries are non-zero

Homework Statement log of 2x2 matrix [4 3] [3 4] Homework Equations e^X= A X= log A The Attempt at a Solution e^A= Ʃ (A^k)/k! then what to do?

can you show me the proof on that formula because it is no where in my book

Homework Statement Find Laplace transformation H(t-1)t^2Homework Equations The Attempt at a Solution [2(e^-s)f(t^2)]/s^3 I'm not sure how to get t^2 in terms of t-1 I know the answer is (2+2s+s^2)/s^3

If a a 1s hydrogen atom is placed in a B field, how many energy states will it split into?

I want to create a handcrank to spin a DC motor at 24000 rpm. The DC motor is an 18V hobby motor from radioshack. Is this possible?

If I wanted to create a hand crank to spin this dc motor... I want to create a handcrank to spin a DC motor at 24000 rpm. The DC motor is an 18V hobby motor from radioshack. Is this possible?

I got it to work

The motor does slow down audibly, I noticed that a few days ago, I also need to place the switch after the capacitor and resistor. I believe that the current will fluctuate, so having the capacitor drain and power the mat steadily is my goal. However, I am not quite sure how long(if it even can)...

I am currently an ENGP major. I am also in NROTC at Tulane University, and slated for Nuclear Engineering after commissioning. I am also being recommended for a R&D job at a base this summer. I'd strongly recommend this major because it will prepare him for almost any engineering field and even...

stark, think of a cell phone charger. The plug that goes into the wall socket is a transformer. It switches AC to DC power. It does not alter the power. It enables the cellphone for instance to draw a charge at its specified voltage and current.

Centaur,I thought by soldering the resistor and capacitor at the same point makes it in parallel?
