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