**Derivative Of Cot**

What is F in Cotex?

I need to find a third derivative of this problem. I took the first derivative, but I don't know what to do when I have f (1 + cot 2 (x)).

f (x) = folding bed (x)

f (x) = csc² (x)

f (x) = 2 csc (x) * csc (x) cradle (x) = 2 csc² (x) cradle (x)

# Use power roll and current roll.

We know that 1 + cot (x) = csc² (x), then f (x) = 2 [1 + cot (x)] cot (x) = 2 cot (x) + 2 cot (X)

f (x) = 2 csc² (x) + 2 (3) pages (x) * csc² (x) = 2 csc² (x) 6 pages (x) csc² (x))
