The first derivative [src]
x*sinh(x) + cosh(x)
xsinh(x)+cosh(x)x \sinh{\left(x \right)} + \cosh{\left(x \right)}
The second derivative [src]
2*sinh(x) + x*cosh(x)
xcosh(x)+2sinh(x)x \cosh{\left(x \right)} + 2 \sinh{\left(x \right)}
The third derivative [src]
3*cosh(x) + x*sinh(x)
xsinh(x)+3cosh(x)x \sinh{\left(x \right)} + 3 \cosh{\left(x \right)}
