Solution

f (y) = \frac{1 + cos ( y )}{1 + sec ( y )}

Solution

Period : 2 π

Domain : 2 πn \leq y < \frac{π}{2} + 2 πn or \frac{π}{2} + 2 πn < y < π + 2 πn or π + 2 πn < y < \frac{3 π}{2} + 2 πn or \frac{3 π}{2} + 2 πn < y < 2 π + 2 πn

Range : - 1 < f (y) \leq 1

Y Intercepts : (0, 1)

Asymptotes : None

Extreme Points : Maximum (2 πn, 1)

+1

Interval Notation
