f(x)=(cos(x))/(cos(x)+1)

Solution

f (x) = \frac{cos ( x )}{cos ( x ) + 1}

Solution

Period : 2 π

Domain : 2 πn \leq x < π + 2 πn or π + 2 πn < x < 2 π + 2 πn

Range : f (x) \leq \frac{1}{2}

X Intercepts : (\frac{π}{2} + 2 πn, 0), (\frac{3 π}{2} + 2 πn, 0), Y Intercepts : (0, \frac{1}{2})

Asymptotes : Vertical x = π + 2 πn

Extreme Points : Maximum (2 πn, \frac{1}{2})
