2secxtanx
| Input |
|---|
| 2 sec(x) tan(x) |
| Alternate form assuming x is real |
| (4 sin(2 x) cos(x))/(cos(2 x) + 1)^2 |
| Roots |
| x = pi n, n element Z |
| Series expansion at x=0 |
| 2 x + (5 x^3)/3 + (61 x^5)/60 + O(x^6) (Taylor series) |
| Derivative |
| d/dx(2 sec(x) tan(x)) = -(cos(2 x) – 3) sec^3(x) |
| Indefinite integral |
| integral 2 sec(x) tan(x) dx = 2 sec(x) + constant |
