Solution:Given x = acos θ, y = b sin θ b 2x 2+ a 2y 2– a 2b 2= b 2(acos θ) 2+ a 2(b sin θ) 2– a 2b 2 = a 2b 2cos 2θ + a 2b 2sin 2θ – a 2b 2= a 2b 2(sin 2θ + cos 2θ) – a 2b 2 = a 2b 2– a 2b 2= θ (∵ sin 2θ + cos 2θ = 1) Question:If tan A = cot B, prove that A + B = 90°. Solution:We have tan A = cot B ⇒ tan A = tan (90° – B) A = 90° – B [∵ Both A and B are acute angles] ⇒ A + B = 90° Question:In a ∆ABC, if ∠C = 90°, prove that sin 2A + sin 2B = 1. Solution:Since ∠C = 90° ∴ ∠A + ∠B = 180° – ∠C = 90° Now, sin 2A + sin 2B = sin 2A + sin 2(90° – A) = sin 2A + cos 2A = 1 Question:If sec 4A = cosec (A – 20°) where 4 A is an acute angle, find the value of A. Solution: We have sec 4 A = cosec (A – 20°) ⇒ cosec (90° – 4 A) = cosec (A – 20°) ∴ 90° – 4 A = A – 20° ⇒ 90° + 20° = A + 4 A ⇒ 110° = 5 A...
