What is a radian?
A radian is a unit of measuring angles, much like degrees. One radian is equal to the angle
made when the radius of a circle is laid along the circumference.

360 degrees is equal to exactly 2 radians (A good way
What is a matrix?
A matrix is a chart containing rows and columns of values and expressions that are manipulated
as a single expression. The length of the rows and columns varies between matrices.
In precalculus, you wont be going very in depth on matrice
What is the unit circle?
The unit circle is simply a circle with a radius of one. It is usually divided to show important
angles in both radians and degrees.

What are Vectors?
A vector is a value that has both direction and magnitude.
Vectors can be added to each other to create a new vector with a combined direction and
magnitude.

What is a logarithm?
A logarithm is the power to which a number has to be raised to produce a given number.
The formula for writing out a logarithmic function is
a x = y
becomes
loga ( y )=x
For example, say we need to know the logarithm to get from 2 to
Limits are going to come up a lot in Calculus, so its important to have a basic understanding of
them ahead of time.
What is a limit?
A limit is a point through which an equation does not pass.
Limits are written using the following equation:
lim f ( x )=
Youve likely learned about sin, cos, and tan, as well as how to use them to find missing angles
and side lengths of right triangles. These are all examples of periodic functions.
What are periodic Functions?
Periodic functions are functions that, when gra
By this point, you may or may not be familiar with the imaginary number i. i is equal to the
square root of negative one ( ). As you know, you cannot take the square of a negative
number, so anytime this pops up, it will simply be written as i, and will b
