[Animated] Trig Limits Made Easy: When to Plug In vs. When to Be Careful

Animated version with step-by-step math walkthroughs powered by Manim. Why can you just substitute values into sine and cosine limits, but tangent sometimes breaks? This video reveals the continuity secrets of trigonometric functions and teaches you a powerful technique for simplifying complex trig limits by pulling continuous functions outside. 📚 Key concepts covered: • Why sine and cosine are continuous everywhere (direct substitution always works) • Where tangent has discontinuities and why (vertical asymptotes at odd multiples of π/2) • The composition property: moving continuous functions outside limits • Step-by-step example: evaluating lim(x→1) cos((x²-1)/(x-1)) • When to stop writing the "lim" notation • Decision framework for approaching any trig limit ━━━━━━━━━━━━━━━━━━━━━━━━ 📖 ORIGINAL SOURCE ━━━━━━━━━━━━━━━━━━━━━━━━ This video distills concepts from:    • Calculus 1 Lecture 1.2:  Properties of Lim...   Full credit to the original creator for the educational content.
