 # Relation f⁻¹(x) with f⁻¹(-x) – Theorems

Relation f⁻¹(x) with f⁻¹(-x) – Theorems Theorem: . Proof: , Let sin⁻¹(-x) = θ . . . (1) -x = sinθ x = -sinθ x = sin(-θ) we know that x ϵ [-1, 1] and  , -θ =sin⁻¹(x) . . . (2) From equation (1) and (2) sin⁻¹(-x) = θ -θ =sin⁻¹(x) ⇒ θ = Read more about Relation f⁻¹(x) with f⁻¹(-x) – Theorems[…] # Interference of Light

Interference of Light When two waves of exactly same frequency travels in a medium, in the same direction simultaneously then due to their superposition, at some points intensity of light is maximum while at some other point’s intensity is minimum. This phenomenon is called Interference of light. It is of following two types (1) Constructive Read more about Interference of Light[…] # National Law University – All India Law Entrance Test (AILET) 2020 Exam Date Released
