The easiest way to do these is to put everything in terms of sin and cos.....so we have

 

 

7 sin (x)  sec (x)

_____________    =

       tan (x)

 

 

7 sin (x)   (1 ) / cos (x)

__________________   =

       sin x  / cos x

 

 

7sin x             cos  x

______  *    _______   =

 cos x             sin x
