Write each expression in terms of sines and or cosines and then simplify sec(x) and cos(x)

Answer 1

To rewrite each expression in terms of sines and cosines, we can use the following trigonometric identities:
1. sec(x) = 1/cos(x)
2. cos(x) = 1/sec(x)

Therefore, in order to simplify sec(x) and cos(x), we can substitute one in terms of the other.

1. Simplifying sec(x):
sec(x) = 1/cos(x)

2. Simplifying cos(x):
cos(x) = 1/sec(x)
