-2sec(pi/2)

- 2 sec (\frac{π}{2})

Undefined

Solution steps

- 2 sec (\frac{π}{2})

Rewrite using trig identities:

sec (\frac{π}{2}) =

Undefined

sec (\frac{π}{2})

Use the basic trigonometric identity:

sec (x) = \frac{1}{cos ( x )}

= \frac{1}{cos ( \frac{π}{2} )}

Simplify

\frac{1}{cos ( \frac{π}{2} )} :

Undefined

\frac{1}{cos ( \frac{π}{2} )}

cos (\frac{π}{2}) = 0

= \frac{1}{0}

\frac{x}{0}

is undefined

= Undefined

= Undefined

= Undefined
