Fast Area of a Parallelogram!
For area, just multiply the base × height. But here's the trick:
Area = a × b × sin(θ) where θ is the angle between them! Try for a = 5, b = 6, θ = 60°!
#MathHacks #GeometryMagic
Rectangle Diagonal Trick!
Find the diagonal using:
d = √(L² + B²). But try this shortcut:
d = √(P²/16 - A). Try for A=24, P=20!
#MathHacks
Heron's Formula Magic!
Find the area of a triangle using sides a, b, c:
Area = √[s(s-a)(s-b)(s-c)], where s = (a+b+c)/2. Try for a=5, b=6, c=7!

The Super Easy Way to Remember Tan & Cot!
Forget formulas! Just use this simple pattern:
🔥 Tan = sin / cos
🔥 Cot = cos / sin
👉 Example:
✔ tan 45° = sin 45° / cos 45° = 1
✔ cot 45° = cos 45° / sin 45° = 1
🔥 Try finding tan 60° using this trick and COMMENT your answer! ⬇️

The 90° Rule to Instantly Find Trig Values!
Did you know?
✔ sin(90° - x) = cos(x)
✔ cos(90° - x) = sin(x)
✔ tan(90° - x) = cot(x)
🔥 So if sin 20° = 0.342, then cos 70° = 0.342 too! 🤯
🔥 Try finding sin 65° using this trick and COMMENT your answer! ⬇️

The Ultimate Trick to Remember All Trig Identities!
Struggling with sin²θ + cos²θ = 1? Use this trick:
🔥 "Some People Have Curly Brown Hair Through Proper Brushing"
✔ Sin²θ + Cos²θ = 1
✔ 1 + Tan²θ = Sec²θ
✔ 1 + Cot²θ = Cosec²θ
🔥 Try finding tan²30° + 1 and COMMENT your answer!⬇️

Approximate value = Lower root + (Number - Lower Square) / (2 × Lower root)
✔ For √78:
8 + (78 - 64) / (2 × 8) = 8 + 14 / 16 = 8 + 0.875 = 8.88
✅ Actual value: 8.83 (Super close!)
🔥 Try √115 and COMMENT your answer! ⬇️
