Question

For what numbers x,-3 SX 3, does sec x=1? Refer to the graph, which shows y secx in blue and y cos x in red. In the interval-3 x 3r, what is the smallest value of x for which sec x= 1? (Type an exact answer, using as needed. Use integers or fractions for any numbers in the expression. Simplify your answer.) Within the given interval, what is the next x-value for which secx 1? (Type an exact answer, using as needed. Use integers or fractions for any numbers in the expression. Simplify your answer.) What other x-values for which secx= 1 are contained in the interval-3 x 3? and 3 2x There are none 2

Explanation / Answer

the smallest value for which sec x = 1

is x = - 2pi ( from the graph )

next value for which sec x = 1 is

x = 0

other value that are contained in the interval is

x = 2pi
