detailed solution

Instruction: You will create two digital task cards that involves proving 2 out of 5 equations(1 involving double-angle and 1 involving half-angle) involving trigonometric expressions with the use of Vedic Mathematics. Answers in your task cards must be viewed by scanning the created QR code per task card. Show your creativity by designing your task cards. 1. 1+cos2 0 2 cos 0 sin 20-cos 0 2 sin 0-1 2. tan - (csc 0) = 1 1 +cos 0 3. 4 cos2 0 + cos 20 = 5 - 6 sin2 0 4. cot 0 sin 20 = 1 + cos 20 5. sin2 - = csc e-cote 2 csc 0
