About

This is meant as a beginner trigonometry course you will find in Geometry course. You do not have to have any experience with trigonometry or right triangles, although it is recommended you have a basic understanding of triangles, especially right triangles. We'll cover all topics in high detail and help you understand trigonometry deeply.

This is NOT built as a trigonometry course for Alg II or Precalculus. You can find another series that covers Alg II/Precal Trig here. Scroll to each week's agenda to find the differences.

Hi! I'm Dean, a Texas high school sophomore who joined Schoolhouse as a tutor to fulfill others' academic journeys, allowing people to develop a passion and excel in academics. I love to tutor and help people grow, hence why I joined this platform. I have a passion for both math and history, and my favorite history subject to tutor is AP Human Geography, while my favorite math subject to tutor is geometry. Outside of academics, I love to play the violin, especially in my high school and local youth orchestra. I also love cats, having 3 of my own. Qualifications to Tutor: Math: - Pre-Algebra - Algebra 1 - Geometry - Algebra 2 - AP Precalculus History: - AP Human Geography
