inverse of f(x)=-arctan(x+1)

Solution

inverse

f (x) = - arctan (x + 1)

Solution

tan (- x) - 1

Solution steps

Solve for

arctan (x + 1), y = - arctan (x + 1)

arctan (x + 1) = - y

arctan (a) = b \Rightarrow a = tan (b)

x + 1 = tan (- y)

Solve for

x, x + 1 = tan (- y)

tan (- y) - 1

Substitute

y = x

tan (- x) - 1
