inverse of-tan((4pi)/9)

inverse

- tan (\frac{4 π}{9})

None

Solution steps

Solve for

tan (\frac{4 π}{9}), y = - tan (\frac{4 π}{9})

tan (\frac{4 π}{9}) = - y

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

\frac{4 π}{9} = arctan (- y)

Solve for

x, \frac{4 π}{9} = arctan (- y)

Since the function is a constant function it has no inverse function

None
