# Basic Numerical Integration: the Trapezoid Rule¶
A simple illustration of the trapezoid rule for definite integration:
$$\int_{a}^{b} f(x)\, dx \approx \frac{1}{2} \sum_{k=1}^{N} \left( x_{k} - x_{k-1} \right) \left( f(x_{k}) + f(x_{k-1}) \right).$$
First, we define a simple function and sample it between 0 and 10 ... | {} |
This function provides point samples from one- and two-dimensional inhomogeneous Poisson processes. The log intensity has to be provided via its values at the nodes of an inla.mesh.1d or inla.mesh object. In between mesh nodes the log intensity is assumed to be linear.
## Usage

There is a ball in a maze with empty spaces and walls. The ball can go through empty spaces by rolling up (u), down (d), left (l) or right (r), but it won't stop rolling until hitting a wall. When the ball stops, it could choose the next direction. There is also a hole in t... | {} |

# Unwanted line breaks after equation tag when using fleqn and leqno
When you use fleqn and leqno and assign your own equations tags with \tag to equations in environments such as gather and align and you assign a tag with a certain length, then there's a line break after the tag. Given the same condition except that ... | {} |
# The Number Guessing Game
Let’s play a game. I think of 5 numbers from 1 to 100. A friend, who has no idea what my 5 numbers are, then tells that you can pick a number from 31 to 60. You win the game if the number you picked is one of the 5 numbers I thought of. Assume that I had no idea that you were going to be res... | {} |
# Number of solution for $xy +yz + zx = N$
Is there a way to find number of "different" solutions to the equation $xy +yz + zx = N$, given the value of $N$.
Note: $x,y,z$ can have only non-negative values.
