Hello, I have had quite a bit of troule with three of the trig problems that i had for homework. If you could show me the steps to get the answer that would be great because i'm sure there's going to be a problem like these on a quiz we will have pretty soon.

1. sec(x)+csc(x)

-------------- Express in 1 trig function

1+(tan(x))

2. cos(x)

----------- + tan(x) Express in 1 trig function

1+sin(x)

3. (sin(x))(cox(x)+sin(x)tan(x))

Thanks ALOT for the help
