# Cosine series of sine
1. Oct 16, 2005
### tiagotorres
I tried to find the cosine series of the function $$f(x) = \sin x$$, using the equation below:
$$S(x) = \frac{a_0}{2} + \sum_{n=1}^{\infty} a_n \cos(nx)$$
where: $$a_n = \frac{2}{\pi} \int_{0}^{\pi} f(x) \cos(nx) dx$$

$$a_0 = \frac{4}{\pi}$$
$$a_n =... | |

# Finding a language for a NFSA
I'm having a bit of trouble determining what language the following non-deterministic finite state automaton accepts.
Assuming the alphabet of this machine is ${a, b}$, I deduced that this automaton would accept words of the following characteristic: a word $w$ would be accepted if $w$... | |

Perimeter of a parallelogram = 2 (L + W) = 2 (√26 + √13) cm. The perimeter of a parallelogram is 2(a + b) where a and b are the lengths of adjacent sides. A parallelogram is a two-dimensional shape. What is the base? An automedian triangle is one whose medians are in the same proportions as its sides (though in a diffe... | |

We propose a fully stochastic trust-region sequential quadratic programming (TR-StoSQP) algorithm to solve nonlinear optimization problems. The problems involve ... | |
# The set of exponential primes
Consider a set of integers $Q$ such that the set of all positive integers $\mathbb{Z}$ is equivalent to the span of ever possible power tower
$$a_1^{a_2^{\ldots a_N}}$$ involving $a_i \in Q$.
In simpler terms. Take the integers, remove all square numbers, cube numbers, fourth powers, ... | |
#### Approach #1: State to State Transition [Wrong Answer]
Intuition and Algorithm
We model the states that blocks can be in. Each state is a binary number where the kth bit is set if the kth type of block is a possibility. Then, we create a transition map T[state1][state2] -> state that takes a left state and a righ... | |
