$\int\limits_{1}^{10} e^.07(10-t)$

so it aint included as the exponent..makes it alittle eas... | {} |

Hi, I wonder whether the expectation operator of the term E[R[w_t]] in equations (11.4.12) and (11.4.13) is unnecessary. And the “E” in (11.4.15) and (11.4.16) seems to be “R”. Thanks a lot.
In inequality 11.4.12, I guess we imply that
E_wt[l(xt, wt)] >= E_wt[E_xt[l(xt, wt)]] = E_wt[R(wt)]
If this is the case, I wo... | {} |
# Linear Transformation and spanning set
I have the following question below:
Let $V$ and $W$ be real vector spaces and $T:V\to W$ be a linear transformation such that $\ker(T) = {0} \subset V$. Let vectors $v_1,v_2,v_3,v_4$ belong to $V$, and $\{T(v_1), T(v_2)\}$ is a generating set for W. Is the set of vectors $v_1... | {} |

# What is the force, in terms of Coulomb's constant, between two electrical charges of 8 C and -15 C that are 9 m apart?
##### 1 Answer
Jun 19, 2018
$- 1.48 \setminus {\text{C"^2"/m}}^{2} \cdot k$
#### Explanation:
Coulomb's law states that:
$F = k \frac{{q}_{1} {q}_{2}}{r} ^ 2$
where:
• $k$ is Coulomb's consta... | {} |

## Exact solution of the 2D Ising model via Grassmann variables
1. Introduction
In 1980 Stuart Samuel gave what I consider to be one of the most elegant exact solutions of the 2D Ising model. He used Grassmann variables to formulate the problem in terms of a free-fermion model, ... | {} |
