PreCalculus Tutoring
Online PreCalculus Tutor — Real Preparation for Calculus
PreCalculus is the foundation to Calculus, and learning it efficiently can help with higher-level thinking. I help high school students master trigonometry, functions, and limits through 1:1 virtual sessions over Zoom or Google Meet.
Topics I cover
Trigonometry
Right triangle trigonometry, soh cah toa, unit circle, trig identities
Functions
Domain & range, transformations, inverses, and composition
Vectors
Vector operations, dot product, cross product, parametric equations
Limits
Evaluating Limits, L'Hôpital's rule, Limits at infinity, continuity
My approach
When introducing a new topic, I begin with a mini-lesson, a few examples, and up to three independent practice exercises. Throughout the lesson, I ask questions to check for understanding and make sure concepts are truly mastered, not just memorized. Every session is customized to your child's goals, pace, and weaknesses.
