Answer 1

I am going to give you some rules, to HELP you with these questions.

For number 1,

\(\LARGE\color{blue}{ \bf \frac{1}{cos(x)}=sec(x) }\) and \(\LARGE\color{blue}{ \bf \frac{1}{sec(x)}=cos(x) }\)

Answer 2

okay and how would you do number 1 like im confused :P

Answer 3

@rockstargirl17 What answer do u get in 1?
