Help with antiderivative

  1. Jan 27, 2012 #1
    1. The problem statement, all variables and given/known data

    Here is the problem: ∫(1+sin(x))/(cos^2(x)) dx

    Also- how do you guys type equations in this? The quick symbols doesn't have a fraction bar or definite integral...

    2. Relevant equations

    sin^2(x)+cos^2(x)=1

    3. The attempt at a solution

    I substituted 1-sin^2(x) for cos^2(x) and factored that to (1+sin(x))(1-sin(x)). The 1+sin(x) in the numerator and denominator cancelled out so the integral is now ∫dx/(1-sin(x)). I don't know what to do now
