# Why does the limit $\lim_{x \to 0} \frac{1-\cos^3 x}{x\sin 2x}$ exist?
The limit does exist and it is equal to $\frac{3}{4}$. We get it using L'Hospital. On the other hand I could write the above limit as: $$\lim_{x \to 0} \frac{1-\cos^3 x}{x\sin 2x} = \lim_{x \to 0} \frac{1}{x\sin 2x} - \lim_{x \to 0} \frac{\cos^3 ... | {} |
# Can we say a function is “unbounded” when we mean it''s tending to infinity?
I'm watching the Limits series on Khan Academy. In many videos Sal repeatedly says that although some people say that functions that tend to infinity have a limit infinity. (For example, in this video, the says that the function $$y = \frac... | {} |
# How exactly does modular exponentiation in Shor's algorithm work?
Consider the modular exponentiation part of Shor's algorithm which in many works is just referred to as $$U_{f}\sum^{N-1}_{x = 0}\vert x\rangle\vert 0\rangle = \vert x\rangle\vert a^{x}\text{ mod }N\rangle$$ where $$a$$ is random number between $$1 < ... | {} |
Reality of the Wavefunction - Complex numbers and Degrees of Freedom in Configuration space
On the "reality" of the wavefunction, there seem to be two schools of thought on why treating $\psi$ as something more than a mathematical tool is erroneous:
1. $\psi$ involves complex numbers. Only Real numbers correspond to ... | {} |

# Two Phase Jets
The phenomena associated with two phase jet dispersion are reviewed by Bricard and Friedel (BricardP:1998). Within a short distance just downstream from the outlet, the flow can experience drastic changes which must be considered for subsequent dispersion calculations. The physical phenomena ... | {} |

# Find an upper bound for a Linear Recurrence
Im having a hard time trying to figure out how to find an upper bound to the following recurrence:
