This series was cancelled by the tutor on March 22, 2025. We're very sorry–you can explore more Geometry series here. All 1:1 and group chats related to this series are disabled 7 days after the last session.

About

Each session, we'll go over several problems about finding cos, sin and Tan, plus lessons if there's beginners. I hope to focus on patterns you'll find within the problems, making it easier if you can recognize them.

View Profile

Hello, my name is Brandy and I'm a sophomore enrolled at a public high school in Texas. I'm here for schoolwork help but also to help tutor others. I can often work harder problems by simply looking at notes and I can tutor mostly any subject. I specialize in any kind of math and science and my history is strong. Not sure if schoolhouse has requirements about this but profile pic credits go to me/TennisMight1 on ToyHouse
