ctg(n+2)

ctg(n+2) means cot(n+2) (in radians).

What would you like to do with it? Here are common options:

• If n is a real variable:

  • Derivative: d/dn[cot(n+2)] = -csc^2(n+2).
  • Integral: ∫ cot(n+2) dn = ln|sin(n+2)| + C.
  • Periodicity as a function of n: cot(x) has period π, so cot(n+2) repeats with period π in n when n is real.

• If you want to express it in terms of cot(n):

  • Use cot(A+B) = (cot A cot B − 1) / (cot A + cot B).
  • So cot(n+2) = (cot n • cot 2 − 1) / (cot n + cot 2). Note cot 2 ≈ −0.4577 (in radians).

• If you want a numerical value for a specific n, just plug in n (in radians).

Tell me which task you need (derivative, integral, expansion, or a numerical value for a particular n), and I’ll show the steps.
