Question

derivate 2sin(X)-cos(x)-cot(x)

Answer 1

d/dx 2sin(x) -cos(x) -cot(x)=
2cos(x) -(-sin(x)) -(-1/(sin(x))^2)
2cos(x) + sin(x) + 1/(((sin(x))^2)

Answer 2

i thought derivate of cot is -csc^2

Answer 3

correct and csc(x) = 1/sin(x), so csc^2 = 1/sin(x)^2.

Answer 4

thank you i see it now :=)

Answer 5

good ; )
