Show that sec'x = d/dx (sec x) = sec x tan x. First, take note that sec x = 1/cos x; d sin x = cos x dx; d cos x = -sin x dx; and d log u = du/u. From the last, we have du = u d log u. Then, letting u = sec x, we have, d sec x = sec x d log sec x; and d log sec x = d log ( 1 / cos x ) = -d log cos x = d ( -cos x ) / cos x = sin x dx / cos x = tan x dx. Thence, d sec x = sec x tan x dx, and sec' x = sec x tan x, which is what we set out to show.
The answer is: L = pi x (D + d)/2 + 2 x ( C x Cos(a) + a x (D-d)/2) where a = arcsin(D-d)/(2 x C) in radians. Where C is the center distance, D is the large pulley diameter, and d is the small pulley diameter.
d=3c
d/dx(x + 2) = d/dx(x) + d/dx(2) = 1 + 0 = 1
d/dx ln(1-x) = 1/(1-x) d/dx 1/(1-x) = 1-x * d/dx 1 - 1 * d/dx(1-x)/(1-x^2 = 1-x * 0 - 1 * 0 - 1/(1-x)^2 = -1/(1-x)^2 --------------

The one in enterna forest. Its not hard to find!
YES
The eon after the Hadean Eon is the Archean Eon. During this eon, significant geological and biological events took place, leading to the development of early life forms on Earth.
They can be accessed only after obtaining the Mystic and Eon Tickets from an official Nintendo event.
2 x 3 x 5 x d x d x d x d x d = 30d5
2 x 3 x 5 x d x d x d x d x d = 30d5
4d x d x d = 4d3
I am currently in the Phanerozoic Eon.
After an eon, the geological time scale progresses to the supereon or "super eon." This term is used to describe an even longer period of time than an eon.
