Trig identities and the unit circle tend to feel like arbitrary rules until someone shows you the geometry underneath them. Felipe approaches trigonometry by building intuition around how sine, cosine, and tangent actually describe relationships in triangles and circular motion — concepts he uses co...

Trig clicks once a student can actually visualize what sine, cosine, and tangent represent on the unit circle — not just memorize SOH-CAH-TOA. Yaajnavalki breaks down identities and angle relationships by connecting them to the real-world engineering applications he studied in his biomedical enginee...

Trig clicks once you stop memorizing identities in isolation and start seeing how they connect — why a double-angle formula is really just the unit circle doing its thing. Daniel's computer science background at Texas A&M means he's constantly using sine, cosine, and angular calculations in code, so...

The unit circle, identities, and inverse trig functions tend to feel like a wall of memorization until someone shows you the geometry underneath. Pranad approaches trig by tying every identity back to right triangles and circular motion — concepts he used constantly in aerospace coursework. Once stu...

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 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 am enrolled in the Mechanical Engineering PhD program at Rice University which will begin Fall 2020, and I am hoping to return to academia as a professor after earning my PhD. In the meantime, I am looking to share my passion for gaining knowledge, specifically in STEM, by educating the up and com...

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...
