Answer:

Cos x

Step-by-step explanation:

HINT:

1 -   Sin² x = Cos² x

Sec x = [tex]\frac{1}{Cos x}[/tex]

Sec x - Sec x*(Sin x)² = Sec x (1 - Sin² x)

                                  = Sec x * Cos²x

                                  = [tex]\frac{1}{Cos x}*Cos^{2} x[/tex]

                                  = Cos x
