simplify sin(-x)cos(-x)sec(-x)

simplify

sin (- x) cos (- x) sec (- x)

- sin (x)

Solution steps

sin (- x) cos (- x) sec (- x)

Use the negative angle identity:

sin (- x) = - sin (x)

= cos (- x) sec (- x) (- sin (x))

Use the negative angle identity:

cos (- x) = cos (x)

= cos (x) sec (- x) (- sin (x))

Use the negative angle identity:

sec (- x) = sec (x)

= cos (x) sec (x) (- sin (x))

sec (x) cos (x) = 1

= 1 \cdot (- sin (x))

Apply rule:

a (- b) = - ab

1 \cdot (- sin (x)) = - 1 \cdot sin (x)

= - 1 \cdot sin (x)

Apply rule:

1 \cdot a = a

= - sin (x)
