- Considering 1,000,000 minds are better than one, I thought I'd post this
- wonderful problem...
-
- _ ______
- ( /
- _) `/ tan x dx
-
-
- Obviously the normal substution t=tan(x/2) won't work since this is no a
- rational function of since and cosine, and integration by parts doesn't
- look too promising...
-
- Mail ranging from insight to a solution, a complete solution, or this is
- not integrable in elementary functions because ________ would be greatly
- appreciated...
-
- Thank you.
