 # Inverse Trigonometric Functions – Form f(f⁻¹(x))

Inverse Trigonometric Functions – Form f(f⁻¹(x)) Function of the form f(f⁻¹(x)): where f(x) is Trigonometric Function (i)Consider function f(x) = sin(sin⁻¹x). Domain of the function is [-1, 1] Also, sin (sin ⁻¹(x)) = x sin(sin⁻¹x) = x for all x ϵ [-1, 1] (ii)Consider function f(x) = cos(cos⁻¹x). Domain of the function is [-1, 1] Read more about Inverse Trigonometric Functions – Form f(f⁻¹(x))[…] # Electrical Conducting Materials for Specific Use

According to Rutherford and Soddy made experimental study of the radioactive decay of various radioactive materials and gave the following the laws: Radioactive decay is a random and spontaneous process. It is not influenced by external conditions such as temperature, Read more about Law of Radioactive Disintegration[…] # Complementary Angles

Complementary Angles Theorem: , Proof: Let . . .(1) Where , , , , , Now sin⁻¹x = θ x = sin θ x = cos (π/2 – θ) cos⁻¹x = π/2 – θ cos⁻¹x + θ = π/2. . . (2) from equation 1 and 2 sin⁻¹x = θ cos⁻¹x + θ = π/2 Read more about Complementary Angles[…] # 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
