Homework Help: Integration question

  1. Oct 17, 2004 #1
    How do you do the following integral without using any special methods, i.e., integration by parts, etc.

    [tex]\int \frac{\tan x}{\sin x} \,dx[/tex]

    ?

    What does [tex]\tan x[/tex] equal? Hint: [tex]\tan x = \frac{\sin x}{?}[/tex] You should remember what the "?" is! :tongue2:

    Anyway, after you make that simplification you will have [tex]\int \sec x \ dx[/tex]

    Unfortunately this integral is tricky to evaluate and DOES require some special tricks to solve (not integration by parts though). Check out this website to see how: integral of secant
