2tanx
Input |
---|
2 tan(x) |
Alternate form assuming x is real |
(2 sin(2 x))/(cos(2 x) + 1) |
Roots |
x = pi n, n element Z |
Series expansion at x=0 |
2 x + (2 x^3)/3 + (4 x^5)/15 + O(x^6) (Taylor series) |
Derivative |
d/dx(2 tan(x)) = 2 sec^2(x) |
Indefinite integral |
integral 2 tan(x) dx = -2 log(cos(x)) + constant |
