❓ Concept ⭐ Parametric Trigonometric Curves in Coordinate Geometry Trig Parametric Curves in 59 Sec Whenever you see x = f ( θ ) , y = g ( θ ) x = f(\theta),\quad y = g(\theta) samajh jao — curve directly nahi diya , balki parameter ke through hide karke diya gaya hai . 1️⃣ Parametric Form — Actual Meaning In parametric equations: x x  and y y  are written in terms of a parameter (usually θ \theta ) As θ \theta  varies → point ( x , y ) (x,y)   moves The path traced by this moving point is the required curve 👉 Direct graph nahi, motion-based definition hoti hai. 2️⃣ Why tan(θ + constant) is Used In JEE, parametric trig curves often look like: x = a tan ⁡ ( θ + A ) , y = b tan ⁡ ( θ + B ) x = a\tan(\theta + A),\quad y = b\tan(\theta + B) Reason 👇 tan-shift identities relate angles linearly Difference of angles becomes constant This allows easy elimination of θ \theta 📌 Especially powerful when: ( θ + A ) − ( θ + B ) = consta...
