Trig identities, unit circle values, and the shift from degree to radian thinking are the exact skills Alex uses constantly in his chemical engineering graduate work — from modeling waveforms to solving differential equations. He unpacks each identity by showing where it comes from geometrically, so...

Trig identities can feel like an endless list of formulas until someone shows you the handful of core relationships everything else derives from. Jake teaches students to prove and manipulate identities by working from sine and cosine definitions outward, which makes unit circle fluency, graphing tr...

Trig identities can feel like an endless list of formulas to memorize, but most of them trace back to the unit circle and a handful of core relationships. Sam teaches students to derive identities from first principles so that verifying equations and solving trig proofs becomes a logical exercise, n...

Trig identities can feel like an endless list until someone shows you the handful of relationships everything else derives from. Aaron, a pure mathematics major at Rice, walks students through the unit circle, inverse trig functions, and identity proofs by emphasizing geometric intuition — why sine ...

The unit circle tends to be where trigonometry either makes sense or falls apart. Leah approaches it by connecting each identity and ratio back to the geometry students already know — once the visual intuition is there, solving equations and graphing sinusoidal functions becomes far more manageable.

I am a licensed physician from Florida who is currently changing careers. I graduated from the University of Pennsylvania in 2009 and have extensive tutoring and editing experience. While a student, I became a certified writing tutor through the Critical Writing Department. Since I completed my writ...

I'm a recent Stanford graduate (Electrical Engineering and Computer Science), and have been working at a major Management Consulting firm for a few years now. I personally scored a 2360 (out of 2400) on the SAT and 35 on the ACT and was successful in gaining admission to several top universities. I'...

I'm available to tutor biology, chemistry, physics, math from Algebra up through AP Calculus, SAT test prep, and French. I've been tutoring students in science and math for 7 years. I also spent 8 months working and studying in France, and have tutored high school and adult students in French. When ...

I am available to tutor middle and high school math, history and test prep. I have tutored math and history in the past and I previously taught a test prep course at a school in Hanoi, Vietnam. I have a lot of experience teaching all the need-to-know tricks to doing great on the SATS/ACTS! When I am...

I am a current student at the University of Chicago. I am working towards a Bachelor of Science in Biological Sciences, and I am on the pre-medical track. I am extremely passionate about tutoring, and I have several years of experience tutoring students in my high school's learning center in various...
