1 tanx 1 tanx

1 tanx 1 tanx

Input
tan(x)×1 tan(x)
Result
tan^2(x)
Alternate form assuming x is real
(sin^2(2 x))/(cos(2 x) + 1)^2
Roots
x = pi n, n element Z
Series expansion at x=0
x^2 + (2 x^4)/3 + (17 x^6)/45 + (62 x^8)/315 + O(x^9)
(Taylor series)
Derivative
d/dx(tan(x) tan(x)) = 2 tan(x) sec^2(x)
Indefinite integral
integral tan^2(x) dx = tan(x) – x + constant
