lecture -02 : Short Tricks | sin⁻¹, cos⁻¹, tan⁻¹ Identities

📘 Inverse Trigonometry Identities & Problems | Ketab Uddin Math | Class Tutorial In this video, we solve important Inverse Trigonometric Function problems from Ketab Uddin Mathematics (Page 287, Example-07). The lecture explains step-by-step derivations, identities, and shortcut techniques to simplify complicated expressions involving sin⁻¹, cos⁻¹, and tan⁻¹. You will learn how to: Derive the identity sin⁻¹x + sin⁻¹y = sin⁻¹(x√(1−y²) + y√(1−x²)) Use the formula tan⁻¹x + tan⁻¹y = tan⁻¹((x + y)/(1 − xy)) Apply the identity 2tan⁻¹x = cos⁻¹((1 − x²)/(1 + x²)) Solve expressions like cos⁻¹(1/√5) − ½sin⁻¹(3/5) + tan⁻¹(1/3) The video also uses geometric triangle methods and trigonometric transformations to make inverse trigonometry easier to understand. 🎯 Perfect for: HSC / College students Competitive exam preparation Anyone learning Inverse Trigonometry identities and problem solving 📚 Topics Covered: Inverse Trigonometric Identities Arcsin, Arccos, Arctan relationships Algebraic simplification techniques Trigonometric triangle method Step-by-step exam problem solving 👍 If this video helps you, Like 👍, Share 🔁 and Subscribe 🔔 for more mathematics tutorials. #InverseTrigonometry #Trigonometry #KetabUddinMath #Arcsin #Arctan #MathTutorial #HSCMath #TrigonometricIdentities
