Reference Angles & ASTC Rule: Find ANY Trig Value Without a Calculator

📓 Interactive Notebook: https://ludium.ai/courses/calculus-1/... Can you find sin(5π/3) without a calculator or unit circle? You already know the answer—you just need the right system. In this video, you'll learn the two-step process that turns ANY trigonometric problem into a simple first-quadrant calculation you've already memorized. Key concepts covered: • The ASTC Rule ("All Students Take Calculus") — which trig functions are positive in each quadrant • Reference Angles — how to find the acute angle to the x-axis for any angle • The Two-Step System — reference angle gives magnitude, ASTC gives the sign • Finding all six trig functions quickly without memorizing hundreds of values • Why reciprocal functions (csc, sec, cot) share signs with their primary functions ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ORIGINAL SOURCE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This video distills concepts from:    • Calculus 1 Lecture 0.3:  Review of Trigono...   Full credit to the original creator.
