How do you do the following integral without using any special methods, i.e., integration by parts, etc.

$$\int \frac{\tan x}{\sin x} \,dx$$

?

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

Anyway, after you make that simplification you will have $$\int \sec x \ dx$$

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
