What is the derivative of f (x) = tan-1(x)?

1.	What is the derivative of f (x) = tan-1(x)?
Answer» The derivative off (x) = tan^-1(x) is1/ (1 + x²) In mathematics, the inverse trigonometricfunction is also known as 'arc functions'. To find the derivative off (x) = tan^-1(x) we will use inverse identity.
