-1,1

Step-by-step explanation:

Answer 2

Maximum value of sec A=$\infty$

Minimum value of sec A=-$\infty$

Step-by-step explanation:

We know that

$Sec A=\frac{1}{cos A}$

Cos 0=1

Sec 0=1

$Cos \pi=-1$

$Sec\pi=-1$

Range of sec x

$(-\infty,-1]\cup [1,\infty)$

Maximum value of sec A=$\infty$

Minimum value of sec A=$-\infty$

Therefore, maximum value of sec A=$\infty$

Minimum value of sec A=$-\infty$
