  • Derivative of cot(x) = -csc²(x)

Step-by-step explanation:

Step 1: Define

g(x) = cot(x)

g'(π/4) is x = π/4

Step 2: Differentiate

  1. Differentiate:                    g'(x) = -csc²(x)

Step 3: Evaluate

  1. Substitute in x:                    g'(π/4) = -csc²(π/4)
  2. Evaluate:                             g'(π/4) = -2
