Hello there,
I assume you mean: .
Recall that .
Be sure to use Chain Rule when differentiating.
Good luck! This should be enough information.
differentiate y= arcosh (4+3x)
could anyone help me please . what differentiation rule do i use with this equaiton and what answer should i get please thankyou !!!!
No, this is the inverse of hyperbolic cosine.
Hyperbolic cosine is
and
See http://en.wikipedia.org/wiki/Hyperbolic_cosine.
The inverse of cosh can be obtained via algebra, letting .
But you can see the derivative of the inverse of cosh at that page, then via the chain rule you can solve this problem.
