Let $$g\in C(\Bbb R)$$ be given, we want to find a solution $$f\in C(\Bbb R)$$ of the equation
$$f(x+1) + f(x) = g(x).$$
We may rewrite the equation using the right-shift operator $$(Tf)(x) = f(x+1)$$ as $$(I+ T)f=g.$$ Formally, I can say that t... | HuggingFaceTB/finemath | |
# General approach to infinite sums
My question is specific to algorithms and models of computation.
I would like to write code to evaluate the following expression quickly and accurately:

Where $$I_\nu(x)$$ is the modified bessel function of the firs... | HuggingFaceTB/finemath | |
# convexity of matrix “soft-max” (log trace of matrix exponential)
In convex optimization it is often convenient to use the following smooth approximation to $\max\{x_1, \ldots, x_n\}$:
$$f_\lambda(x_1, \ldots, x_n) = \frac{1}{\lambda}\log \sum_{i = 1}^n{e^{\lambda x_i}}.$$
Above $\lambda > 0$ is a parameter. It's e... | HuggingFaceTB/finemath | |
# Is (0,1) a solution to 1-x>=3y, 3y-1>2x?
Jul 20, 2017
See a solution process below:
#### Explanation:
Substituting $0$ for $x$ and $1$ for $y$ in the first inequality gives:
$1 - 0 \ge 3 \cdot 1$
$1 \ge 3$
This is not true therefore $\left(0 , 1\right)$ is not a solution. | HuggingFaceTB/finemath | |

## Conversion formula
The conversion factor from ounces to pounds is 0.0625, which means that 1 ounce is equal to 0.0625 pounds:
1 oz = 0.0625 lb
To convert 64.9 ounces into pounds we have to multiply 64.9 by the conversion factor in order to get the mass amount from ounces to pounds. We can also form a simple propo... | HuggingFaceTB/finemath | |

1. ## Calculas question
I hope this is the right area to post this question.
Find the equation of the tangent to the curve y=2/x+1 at the point where x=3.
y=2/x+1
y=2/4
=1/2 (3,1/2)
2(x+1)^-1
-2(x+1)^-2
-2/(x+1)^2
2/(3+1)(3+1)
