1 tan2x

1 tan2x

Input
1 tan(2 x)
Result
tan(2 x)
Alternate form assuming x is real
(sin(4 x))/(cos(4 x) + 1)
Roots
x = (pi n)/2, n element Z
Series expansion at x=0
2 x + (8 x^3)/3 + (64 x^5)/15 + O(x^6)
(Taylor series)
Derivative
d/dx(1 tan(2 x)) = 2 sec^2(2 x)
Indefinite integral
integral tan(2 x) dx = -1/2 log(cos(2 x)) + constant
