We're going to be covering
-Polynomials
-Vectors
-Complex Numbers
-Rational Functions
-Exponents/Logarithms
-Function Transformations
-Linear Transformations using Matrices
-Types of triangles

ā ATTENDANCE POLICY
Attendance is optional but highly recommended since topics build on each other; however I understand that everyone has a busy schedule, so if you can't make it and want a catch-up session just ask!

About the Tutor
PL
JG
Hey, my name's Jose, and I'm currently a senior. I'm about the biggest Indie music fan there is, I love 80s movies (John Hughes goat), and reading in my spare time. I enjoy math because it allows me to express myself artistically, and tutor for the mere sake of those aha moments. I've gotten 5s on AP Spanish Lit and AP English Lang, and I've taken Multivariable Calc and Linear Algebra (which I hope to tutor soon!) I'm currently taking AP Physics C and Real Analysis.

Review
-Reviewing quadratic factorization
-Learn about the features of polynomials represented visually in graphs including factors (zeros), the multiplicity of their zeros, the graphs y-intercept, and end behavior (odd or even or none).

Session 5
Trigonometry
Hey guys,
Today we're going to learn the trigonometric ratios (SOHCAHTOA), reciprocal ratios, and build some intuition around them (it would be helpful to know about Similarity beforehand). We'll find the lengths of missing sides of right triangles, learn about complementary angles, and do some other practice.

Session 9
Complex numbers
Hey guys, these two sessions will be on Vectors, but I put it as about Complex Numbers because their relation will lay the foundations for our understanding of Complex Numbers.
- What is a Vector? What are n-vectors?
-Zero vectors
-Vector quantities vs Scalar quantities
-Finding the x and y component of a vector, adding and subtracting vectors together (the parallelogram rule
-The argument and modulus of a vector, what they are and how to derive them (inverse trig functions)
-Some more advanced problems on vectors from Khan Academy

Trigonometry
Hey guys, today we're going to be plotting the values of trigonometric functions that we derived using the unit circle onto a graph; then we'll play around with inverse functions and make the trigonometric functions invertible (For background knowledge on making functions invertible, go to https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:composite/x9e81a4f98389efdf:invertible/a/intro-to-invertible-functions). We'll also determine the domain and range of these inverse functions and see their graphs as well.

Trigonometry
Hey guys, today we're going to take a look at the features of sinusoidal (sine and cosine) functions today: amplitude, period, midline, and phase shift, and how each of these features corresponds to a different part of the sinusoidal equation af(b(x+c))+d, where f is either sin or cosine.

We'll also cover vectors and matrices--what they are, how to add and subtract them, as well as multiply them.
We'll use this to prove the rotation matrix, a linear function to rotate functions or points by a given angle.
