`+ \ C` Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
Recall the integral formulas for hyperbolic functions, particularly the one involving the product of `csch` and `coth`. Consider how this formula changes when dealing with `4 x + 9` instead of just `x`.
Be sure your variables match those in the question `-csch(4 x+9)/4`
