Trigonometry
What are Pythagorean identities?
This test tells you whether a given graph is a function or not.
What is a vertical line test?
This product of two vectors gives a scalar value instead of another vector.
What is the dot product?
This number system includes both real numbers and nonreal numbers.
What are complex numbers?
This is Mr. Rhee's favorite song from Freaky Friday.
What is Biology?
This number equals sec2x - tan2x.
What is one?
These formulas have to do with sums and products of polynomial roots.
What are Vieta's Formulas?
Multiplying a vector by this can change the vector’s length, and if it is negative, it makes the vector point in the opposite direction.
What is a scalar?
This theorem says that when a polynomial is divided by (x - a), the remainder is f(a).
What is the remainder theorem?
This is also called "Five-in-a-Row".
What is Gomoku?
The functions y=sinx and y=tanx are both this type of function because their graphs are symmetric about the origin.
What are odd functions?
This is the simplest form of a type of function before any transformations.
What is a parent function?
Multiplying a square matrix by this matrix does not change the original matrix.
What is the identity matrix?
This theorem gives a list of possible rational zeroes of a polynomial using the factors of the constant term and the leading coefficient.
What is the Rational Root Theorem?
Mr. Rhee joined Mirman this year.
When is 2023?
For a sine or cosine graph, this is half the positive difference between the maximum value and the minimum value.
What is the amplitude?
These functions are symmetric over the y-axis.
What are even functions?
The absolute value of the dot product of one vector and the cross product of the other two gives the volume of this 3D solid.
What is a parallelepiped?
The quadratic formula is derived by using this algebraic process.
What is completing the square (CTS)?
This was the 8th grade musical last year.
What is Legally Blonde?
This theorem lets you raise a complex number in polar form to a power by raising its distance from the origin to that power and multiplying the angle by the power.
What is De Moivre’s Theorem?
This is another name for a greatest integer function, and also used in Desmos.
What is a floor function?
A square matrix does not have an inverse if this value is 0.
What is the determinant?
This theorem guarantees that a degree n polynomial has n complex roots when multiplicity is counted
What is the Fundamental Theorem of Algebra?
This was the 8th grade musical two years ago.
What is School of Rock?
