With the following code segment ;(adsbygoogle = window.adsbygoogle || []).push({});

limit((sin(z+h)-sin(z))/h,h,0)

matlab gives the result cos(z). (which is the differential of the sin(z)).

However, with the code ;

limit((sinh(z+h)-sinh(z))/h,h,0)

matlab gives an absurd result;

limit((sinh(z+h)-sinh(z))/h,h = 0)

newertheless, the result should be cosh(z). Why does matlab makes such a wrong calculation also what is the meaning of this result? Does anybody have an idea about that?
