\[x \neq \frac{ \Pi }{ 2 }, \frac{ 3\Pi }{ 2 }, \frac{ 5\Pi }{ 2 }, . . . . . . .\] \[range : y \ge 1 and y \le 1\]

Ahm @yaho021 Domain=R{x=n(pi/2)} Where pi=1,3,5........ Couldn't get the range thing :/

How do we determine the range ?

\[\sec(x) = \dfrac{1}{\cos(x)}\]The range of values is \((\infty , \infty)\).

No, I meant when \(\cos(x)\) tends to \(0\) from the right side, then \(\sec(x) \) goes towards \(\infty\). And when it tends to \(0\) from the left, then \(\sec(x)\) goes towards \( \infty\).

So the range is all real numbers.

Okay someone said it would be All real numbers(1,1)

That's the range of \(\cos(x)\), not \(\sec(x)\)

Think about the range of \(\dfrac{1}{x}\). Whenever \(x\) is near zero, \(\dfrac{1}{x}\) is near infinity.
