    why when we found cosh^2(x) we ended up integrating just cosh ?

    Why dy/dx is not - hsinhx

      The function is sinh, not sin

      @@MathsWithJay again one more doubt.. Why are we differentiating sinh it is constant in terms of x and differentiation of sinx is - cosx

      Note that sinh and cosh are the hyperbolic functions: en.wikipedia.org/wiki/Hyperbolic_functions
      So they are not sin and cos.
      Does that answer your question?
