2cotx
Input |
---|
2 cot(x) |
Alternate form assuming x is real |
-(2 sin(2 x))/(cos(2 x) – 1) |
Roots |
x = 1/2 (2 pi n + pi), n element Z |
Series expansion at x=0 |
2/x – (2 x)/3 – (2 x^3)/45 – (4 x^5)/945 + O(x^6) (Laurent series) |
Derivative |
d/dx(2 cot(x)) = -2 csc^2(x) |
Indefinite integral |
integral 2 cot(x) dx = 2 log(sin(x)) + constant |
