About

When we think of trigonometry (trig), we might be overwhelmed, And for good reason—we've got three new operations, and π shows up everywhere (and not for the area or circumference of a circle)!

If you relate, then this Trigonometry series would be just right for you! These are simply the basics, but they will provide a great foundation for harder mathematics courses, such as calculus courses (AP and college). Most of all, they serve as a good way to ease into the world of trig.

I will be basing my curriculum on the Khan Academy Precalculus Trigonometry unit (https://www.khanacademy.org/math/precalculus/x9e81a4f98389efdf:trig), so feel free to peruse the catalog if your curiosity is nagging at you.

I'm looking forward to meeting and learning with you all throughout the duration of this series!

ADDENDUM: I apologize for any scheduling inconveniences that this series may have caused, especially as it is later in the day.

✋ ATTENDANCE POLICY

Only our sessions about new content are required—all catch-up sessions are optional. If you complete the unit test early and show it to me, then you are also free to end the series early!

About the Tutor

My name is Daphne, and I'm from New York. My two favorite subjects are science and math. In my free time, you may catch me conspiring with my Rubik's Puzzle collection, playing random story-driven games (I love pixels!), drawing and burning myself out while doing so, or hugging stuffed animals.
