# 8.5 | Partial Fractions
A rational function
$$\frac{P(x)}{Q(x)}$$
with the degree of $$P(x)$$ less than the degree of $$Q(x)$$, can be rewritten as a sum of fractions as follows:
• For each factor of $$Q(x)$$ of the form $$(ax+b)^m$$, introduce terms

# Random variables and their properties
Properties of PMF:
1. $p(x) \geqslant 0 \forall x$
2. $\sum_{xin D}^{ } p(x) = 1$
Expected value : [E[X] = $mu$]
1. $E[X] = \sum x_ip(x_i)$
2. $E[f(x)] = \sum f(x_i)p(x_i)$
3. $E[aX+b] = aE[X] + b$
Variance Var[x]:
1. $Var[X] = E[(X-\mu)^2 ] = E[(X-E[X])^2] = \sigma ^2$

# 8.5: Variables
It seems like a good idea at this point to think in a very general way about which variables are likely to be important in problems of sediment transport, and to organize those variables into a set of dimensionless variables that is likely to be useful as a framework from which to simplify or (complex... | {} |
# To Infinity…and Beyond!
In researching Gödel’s Incompleteness Theorem, I stumbled upon an article that stated no one has proven a line can extend infinitely in both directions. This is shocking, if it’s true, and after a quick Google search, I couldn’t seem to find anything that contradicts the claim. So, in the spi... | {} |
