His science training gave him deep comfort with the trigonometric relationships that underpin physics and calculus.

I am passionate about helping students when they are feeling stuck or frustrated, especially in math classes. For 2 years, I have tutored Algebra, Geometry, and Pre-Calculus. I have found it is most helpful to reteach concepts in a setting where students can ask questions along the way. When students feel comfortable asking for help and can work through adversity, they are better able to succeed in the classroom and learn valuable problem-solving skills they can use in the future.

Hi there, I'm Piyush, a freshmen at Oregon state university. I believe every student has the capacity to master complex topics and build confidence in themselves given enough time and the right tools. I do just that and teach my students how to think instead of what to think. I use analogies, visual indicators and various different explanations to teach a concept so it sticks. I am dynamic enough to change my tutoring style based on the kind of student I am teaching, whether it be direct or patient depending on the mindset of the student. I constantly review the change I am causing in the students with consistent skill-checks and mini-quizzes where I have the student explain the concept back to me to check their understanding. Overall, I am focused on creating the best tutoring experience for my students which includes keeping up with the curriculum myself. I am constantly studying advanced topics to make sure my explanations are as accurate as possible.

Most students hit trig after a comfortable run through algebra and geometry, then suddenly face a subject that feels like a different language. Matthew's approach is to slow down at that transition point — grounding right-triangle ratios and angle measurement in concrete problems before moving into graphing and identities. His 1500 SAT and broad math teaching background mean the algebraic foundations students need for trig are always within easy reach.

The unit circle is where most trigonometry students either click or stall, and everything from graphing sine and cosine to verifying identities depends on truly internalizing it.
