What are first order linear?
This is the resulting transformation of f(-x).
What is horizontal reflection?
The magnitude of a complex number.
What is the modulus?
This happens when two vectors are perpendicular.
When is the scalar product (dot product) equal to zero?
When this happens, the denominators on a tree diagram decrease from left to right.
What is "without replacement?"
It is the test to determine whether an Euler's Method approximation is above or below the actual value.
What is the second derivative test?
These are the three different scenarios involving discriminant and roots.

What is a logistics function?
a1(1-rn )/(1 - r)
What sum of a finite geometric series?
(rcisx)n = rn (cos nx + i sin nx)
What is De Moivre's Theorem?
To find this in vectors, you multiply the ones that match and add all of those products together.
What is the dot product? (scalar product)
This tool measures the average of the squared deviations of each data value from the mean.
What is the Variance?
Is a line that joins neighboring points with the same gradient, much like contour lines on a map joins neighboring points with the same heights.
What is an isocline?
2 - log3 (x+7) = log1/3 (2x)
What is 7/17?
The process where you multiply the radii and add the angles of complex numbers.

What are Mutually Exclusive Events?
It is the key step from differential calculus used in simplifying one side of a first order linear differential equation into: the integrating factor x the function or m(x) y(x).
What is the product rule?
Given that tan (A+B) = (tan A + tan B)/(1- tanAtanB) and tan(1/5) + tan(1/8)= tan (1/p). Find p.
