A set is a well-defined collection of distinct objects, considered as an object in its own right. Sets are typically denoted by curly braces, for example, .
input text value
Define a subset.
A subset is a set in which all of its elements are also contained within another set. If A is a subset of B, then every element of A is also an element of B, denoted as A ⊆ B.
input text value
What is a power set?
The power set of a set S is the set of all possible subsets of S, including the empty set and S itself. If S has n elements, then the power set of S has 2^n elements.
input text value
Explain the principle of mathematical induction.
Mathematical induction is a proof technique used to prove a statement for all natural numbers. It consists of two steps: the base case, where the statement is proven for the initial value, and the inductive step, where the statement is proven for n+1 assuming it holds for n.
input text value
What is a function in the context of discrete mathematics?
A function is a relation between a set of inputs and a set of permissible outputs where each input is related to exactly one output. Functions are often denoted as f: A → B, where A is the domain and B is the codomain.
input text value
Define a bijective function.
A bijective function is a function that is both injective (one-to-one) and surjective (onto). This means every element of the codomain is mapped to by exactly one element of the domain.
input text value
What is a graph in discrete mathematics?
A graph is a collection of nodes (or vertices) and edges (or arcs) that connect pairs of nodes. Graphs can be used to model relationships between objects.
input text value
Describe an undirected graph.
An undirected graph is a graph in which the edges have no direction. The edge is identical to the edge , meaning the connection between nodes is bidirectional.

Nadat ik Knoowy ontdekt heb, ga ik regelmatig op zoek naar eventuele bruikbare samenvattingen! Heel erg handig!
Knoowy is voor mij de perfecte service om een centje bij te verdienen! Die samenvattingen moet ik sowieso maken, dus waarom ze niet uploaden en wat bijverdienen?
Knoowy is een makkelijk platform om in contact te komen met studenten die extra hulp nodig hebben in de voorbereiding van examens, het maken van verslagen of ander huiswerk.
Goed voor als je een samenvatting nodig hebt of de leerstof niet zo goed snapt, maar ook voor als je bijles nodig hebt.
Een echte aanrader! Je vindt er heel wat nuttige samenvattingen!
Een handige site voor het aankopen van samenvattingen voor examens.
Studiehulp geven aan studenten die het nodig hebben vind ik leuk om te doen, en ik verdien er wat mee zodat ik leuke dingen kan doen naast mijn studie.
De samenvattingen zijn goed om te gebruiken als je te laat bent met leren of slecht bent in samenvatten.
