if you can't help me with my first question hopw you can help me with this one.


thanx to anyone who can help

From the definition of the sec and csc functions, and the tan function,

sec(-x)/csc(-x) = sin(-x)/cos(-x)
= tan(-x)

However, tan (x) does not equal tan (-x). They have opposite signs

Are you sure you copied the problem correctly?
