# Math Help - I need help with partial fractions
1. ## I need help with partial fractions
I need to compute this integral:

I think I should use the partial fraction method to simplify the fraction

(1-x^2)/(x^3+x)= A/x + B/ (1+x^2)
Therefore

At what distance from the center intersects sphere with radius R = 56 plane, if the cut area and area of the main sphere circle is in ratio 1/2.
Correct result:
x = 39.6
#### Solution:
$x=r\sqrt{1-\frac{a}{b}}=56\sqrt{1-\frac{1}{2}}=39.6$

# Solving Second Order Differential Equations.
How would you go about solving the following system of ODEs:
\begin{align*} & x''(t) - \frac{2}{y}x'(t) \ y'(t) = 0 \ & y''(t) + \frac{1}{y} \big(x'(t) - y'(t)\big) = 0 \end{align*}
Any help would be very much appreciated!

# The stationary tower and supercompactness
I'm currently reading through Larson's book on the stationary tower and a point confused me.
Let $\delta$ be Woodin and let $j:V\to M\subseteq V[G]$ be an elementary embedding associated with the (full) stationary tower $\mathbb P_{<\delta}$. Then $V[G]\models {^{<\delta}}M... | |
# Crooked Maps in Finite Fields
Abstract : We consider the maps $f:\mathbb{F}_{2^n} →\mathbb{F}_{2^n}$ with the property that the set $\{ f(x+a)+ f(x): x ∈F_{2^n}\}$ is a hyperplane or a complement of hyperplane for every $a ∈\mathbb{F}_{2^n}^*$. The main goal of the talk is to show that almost all maps $f(x) = Σ_{b ∈... |
