Mathematics for Computing Flashcards
What is a set in math?
A set is a collection of unique items, like numbers or objects.
What is the union of two sets?
The union of two sets combines all the items from both sets, without repeats.
What is the intersection of two sets?
The intersection contains only the items that are in both sets.
What is a function?
A function connects inputs to outputs, where each input gives one output.
What is a linear equation?
A linear equation is a math formula that makes a straight line, like
y=mx+b.
What is the slope of a line?
The slope shows how steep a line is, calculated as how much
y changes when x changes.
What is a matrix?
A matrix is a grid of numbers arranged in rows and columns.
What is matrix multiplication?
Matrix multiplication involves combining rows and columns to create a new matrix.
What is a vector?
A vector is a list of numbers that represent both direction and size (like an arrow).
What is the dot product of two vectors?
The dot product multiplies matching numbers in two vectors and adds them up.
What is exponentiation?
Exponentiation is multiplying a number by itself a certain number of times, like
2 3 =2×2×2.
What is a logarithm?
A logarithm is the opposite of exponentiation, showing the power to which a number must be raised.
