y= 1/(2cos(x))

Solution

y = \frac{1}{2 cos ( x )}

Solution

Period : 2 π

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

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

Y Intercepts : (0, \frac{1}{2})

Asymptotes : Vertical x = \frac{3 π}{2} + 2 πn, x = \frac{π}{2} + 2 πn

Extreme Points : Minimum (2 πn, \frac{1}{2}), Maximum (π + 2 πn, - \frac{1}{2})

Interval Notation

Domain : [2 πn, \frac{π}{2} + 2 πn) \cup (\frac{π}{2} + 2 πn, \frac{3 π}{2} + 2 πn) \cup (\frac{3 π}{2} + 2 πn, 2 π + 2 πn)

Range : (- \infty, - \frac{1}{2}] \cup [\frac{1}{2}, \infty)
