Prove that sin square A+ cos square A=1 |
|
Answer» HEY !!! we know that h² = b² + p² -------1) heighpotenius = base² + perpendicular² we also know that sin¢ = p/h cos¢ = b/h so , sin²¢ + cos²¢ (p/h )² + (b/h )² => b² + p² /h² = h²/h² (from EQUATION 1st) = 1 ._____________ 2nd method sin²¢ + cos²¢ 1 - cos²¢ + cos²¢ ✔•°• sin²¢ = 1 - cos²¢ = 1 prooved **************************** Hope it HELPS you !! @Rajukumar111 |
