1 + cosh(3*x) + sinh(3*x)
-------------------------
1 + cosh(x) + sinh(x)
$$\frac{\sinh{\left(3 x \right)} + \cosh{\left(3 x \right)} + 1}{\sinh{\left(x \right)} + \cosh{\left(x \right)} + 1}$$
3*x
1 + (cosh(1) + sinh(1))
--------------------------
x
1 + (cosh(1) + sinh(1))
$$\frac{\left(\sinh{\left(1 \right)} + \cosh{\left(1 \right)}\right)^{3 x} + 1}{\left(\sinh{\left(1 \right)} + \cosh{\left(1 \right)}\right)^{x} + 1}$$
2*x x
1 + (cosh(1) + sinh(1)) - (cosh(1) + sinh(1))
$$\left(\sinh{\left(1 \right)} + \cosh{\left(1 \right)}\right)^{2 x} - \left(\sinh{\left(1 \right)} + \cosh{\left(1 \right)}\right)^{x} + 1$$
1 + (cosh(1) + sinh(1))^(2*x) - (cosh(1) + sinh(1))^x
