    Trig Identity

    Hey guys, I need a good refresher on identities. It has been awhile and Finals week is coming up. I'm stuck on this practice question our teacher gave us:

    Simplify: \frac{1+secx}{sinx+tanx}

    Edit: for some reason latex isn't working right for me but the following equation is as follows:
    (1+secx)/(sinx+tanx)

    I believe this simplifies to cscx but I can't seem to figure out how to get to it.

    Start by writing everything in terms of sin(x) and cos(x), then getting common denominators...

    tan(x) can be written as sin(x)/ cos(x) = sin(x)*sec(x),. Put this in the problem and simplify.
