# Algebra 2 w/Trig

Next session on Jul 3, 2022

Hosted by Jose Roberto Cossich G

### Series Details

Hey guys, wanna get ahead of the curve? Wanna catch-up or reinforce your skills? I'm hosting this series because I really enjoyed my Algebra 2 and Trigonometry series in the past and because of popular demand.
In this series we'll cover:
-Polynomials (polynomial arithmetic, factoring, remainder and factor theorem, solving equations, features of graphs)
-Vectors
-Complex Numbers and Equations
-Rational Functions
-Exponents/Logarithms (Arithmetic, Algebra, and Graphs)
-Function Transformations
-Types of triangles,
- General Triangle Properties
-Circumcenter, Centroid, Altitudes, and Medians
-Triangular Pyramids and Prisms (and their brain bending properties :)
-Right Triangle Trigonometry (SOHCAHTOA, Complementary Angles, Reciprocal Trigonometric Ratios, etc.)
-Unit Circle and Trigonometric Identities/Values
-Trigonometric Functions
-Inverse Trigonometric Functions
-Sinusoidal Graphs/Equations
-Other Trigonometric Identities

✋ ATTENDANCE POLICY

Catch-up sessions are always available. Notes will also be posted.

Hi, my name's Jose, I'm a high school sophomore and an international student. I love to travel, listen to music, watch movies, (I'm a total Star Wars and 80's geek), and do photography, 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'm currently taking AP Calculus BC, hope to see you soon!

Session 19

#### 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 20

#### Trigonometry

Hey guys, today we're going to go over the law of sines and cosines (and their proofs) to find the missing sides of arbitrary triangles (and provide some more intuition to some congruence theorems using these laws)

Jul

Session 21

#### Trigonometry

Hey guys, today we'll learn what radians are and how to convert between them and degrees. Then we'll go over the Unit Circle, trig identities/values that we can derived from the unit circle, and then we'll practice computing trig values.

Session 22

#### Trigonometry

Hey guys, today we're going to be reviewing everything we've learnt so far:
-Triangle types, finding angles.
-Medians, circumcenters, centroids of triangles
-Pythagorean Theorem (& Special Right Triangles)
-SOHCAHTOA and reciprocal trigonometric ratios

Jul

Session 23

#### Trigonometry

We'll be covering the Unit Circle and the Unit Circle Identities today.
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.Then, we'll practice computing trig values.

Session 25

#### 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.
