Sine, Cosine, and Continuous Fractions
Where can I find development of functions like sine or
cosine in continued fractions?
You can find this info in "A Concise Encyclopedia of Mathematics" by Eric
published be CRC Press.
If you mean series expansion of these functions, you can find them in many
college level math books.
The answers, however, are:
sin(x) = x - x^3/3! + x^5/5! - ....
cos(x) = 1 - x^2/2! + x^4/4! - ....
