3 tan x

3 tan x

Input
3 tan(x)
Alternate form assuming x is real
(3 sin(2 x))/(cos(2 x) + 1)
Roots
x = pi n, n element Z
Series expansion at x=0
3 x + x^3 + (2 x^5)/5 + O(x^6)
(Taylor series)
Derivative
d/dx(3 tan(x)) = 3 sec^2(x)
Indefinite integral
integral 3 tan(x) dx = -3 log(cos(x)) + constant
