It is becoming increasingly common to see large collections of network data objects — that is, data sets in which a network is viewed as a fundamental unit of observation. As a result, there is a pressing need to develop network-based analogues of even many of the most basic tools already standard for scalar and vector... | |

We previously learned about the problem of predicting the folding of a protein, that is, given a chain of amino acids, find its final 3D structure. This time we’re interested in the reverse problem, that is, given a 3D structure, find some chain of amino-acid that would lead to that structure once ful... | |

# Finding the Volume of a Cone
GEOM-4RS@ZH
Find the volume of a right circular cone in which the height (H), the radius (R), and the slant height (S) of the cone form a 30-60-90 triangle. The radius of the cone and its slant height form the 60 degree angle, and the diameter of the base of th... | |

As each sum develops it should become clear that the last number in each sum is triangular. So for $S_n$, the last number in the sum is the $n^{th}$ triangular number $= n(n + 1)/2$. Bearing ... | |

# Coprime
## Definition 1
Two integers are coprime if and only if the only integer that divides both of them is $$1$$.
## Definition 2
$$\forall a,b \in \mathbb{Z} : a \perp b \Leftrightarrow gcd(a, b) = 1$$
THEOREM $$\forall a \in \mathbb{Z} : 1 \perp a$$

# What do parameters like Torque (Nm) mean for ebikes?
Motor Torque is the characteristic which reflects the traction (thrust) and is important for climbing up hills.
• The traction force equals Torque divided by wheel radius (F=T/R).
• The more torque at the wheel gives you a higher grade-ability.
• The smaller whee... | |
