Part 1 Intro to Unit Circle

All shall fear… THE UNIT CIRCLE ⬇️ Here are 3 “tricks” to survive the Unit Circle without losing your mind: 1. The “Mirror” Hack: Only learn the first quadrant and just “reflect” the values into the other three sections—because why do 4x the work when you can just copy-paste your own confusion into the rest of the circle? 2. The “Gang Sign” Method: Master the “Left Hand Rule” for sine and cosine values so you can look like you’re throwing up secret handshakes or doing a magic trick in the middle of the exam while everyone else is panicking. 3. The “Actually-Passing” Cheat Code: Stop pretending you’re going to “grind” through a 50-page textbook and just upload “The Unit Circle.pdf” directly to Learnable to get a 3D visual explanation that actually makes sense. It’s much harder to fail when the math is literally being drawn out for you in 3D. Drop a 🤡 if Pre-Calc ruined your life. Then go click the link in my bio so it never happens again. #precalc #unitcircle #academiccomeback #learnable #mathhacks

Remember this from your trigonometry class? It never goes away! What a remarkable construction this is! Circles, triangles and sinusoidal curves oh my!

Unit Circle Basics Positive x-axis → (1,0) → 0 or 2pi Positive y-axis → (0,1) → pi/2 Negative x-axis → (-1,0) → pi Negative y-axis → (0,-1) → 3pi/2 Remember: x = cos(θ) y = sin(θ) So every point on the Unit Circle is (cos(θ), sin(θ)).

It was so clear on the lesson… what happened before the exam? #trig #unitcircle #math

This visual represents the unit circle, and how the value of the sine of theta varies as the angle theta increases. Sine of theta can be thought of as the y coordinate as we move along the unit circle. The reason for this is because the unit circle has a radius of 1 by definition, which is the hypotenuse of the right angled triangle. Now, as we move along the arc of the circle, starting from the coordinate (1,0), our x and y positions change. We can call the angle between the x axis and the hypotenuse theta, and by simple trigonometry we see that the y coordinate is always the sine of theta!

Sine, Cosine, and Tangent Don’t actually come from triangles. They originate from the Unit Circle. Understanding this is key to mastering trig at a higher level. Save this if you want to level up your trig knowledge. #trigonometry #unitcircle #hscmaths #mathsmadeeasy

Radians are better once you get familiar with them. #trig #precalc #unitcircle #radians
