$-2x^{3}+8x^{2}-19x-2$
We are asked to subtract $(9x+8)$ from the sum of $(3x^{2}-2x-x^{3}+2)$ and $(5x^{2}-8x-x^{3}+4)$. This is equivalent to the expression $(3x^{2}-2x-x^{3}+2)+(5x^{2}-8x-x^{3}+4)-(9x+8)$. We can subtract the third term from the first two terms by adding the op... | {} |
I am trying to gather historical data for experimental reasons (intellectual curiosity) and am having trouble understanding how that data is calculated. First some data gathering on AAPL from Feb. 10th, 2015 at opening.

# Application of Dynkin's π-λ theorem
When dealing with collections of sets, Dynkin’s systems provides simple but powerful tool for extension of properties in smaller collections to bigger ones.
First, we define $\pi$ and $\lambda$-systems.
A collection of sets $\mathcal{P}$ is a $\pi$-system if $A, B \in \mathcal{... | {} |
# Revision history [back]
The following was working for me. A is a matrix of shape 6x35, taken (almost) randomly. (There was a rank check after getting it.) C is the linear code associated to it. B is the parity check matrix for the code.

# How do I plot a line delineating a subset of values on a 3D surface plot?
I have the following surface plot:

# Mechanics question
Suppose I am standing at the top of a cliff which is a vertical distance (d) above the ground. Now, if I jump off the slide at an angle beta upwards at an initial velocity (v), I will travel a horizontal distance of (R). I have proved the first part of the question which shows these quantities are... | {} |
## Abstract
Geophysical processes are often characterized by long-term persistence. An important characteristic of such behaviour is the induced large statistical bias, i.e. the deviation of a statistical characteristic from its theoretical value. Here, we examine the most probable value (i.e. mode) of the estimator o... | {} |

## A neat method of integration required for marginals from a joint pdf
Hi,
I wonder if anyone can show me a neat way to do integrate out x and then y to obtain marginal pdfs given the joint
$f_{X,Y} (x, y) = y \cdot \exp(-xy - y)$
where
$x \geq 0, y \geq 0$
I'm getting tied in knots with integrating by parts agai... | {} |
