Ha introducido [src]
x*sech(x)
$$x \operatorname{sech}{\left(x \right)}$$
x*sech(x)
Gráfica
Primera derivada [src]
-x*sech(x)*tanh(x) + sech(x)
$$- x \tanh{\left(x \right)} \operatorname{sech}{\left(x \right)} + \operatorname{sech}{\left(x \right)}$$
Segunda derivada [src]
/               /           2   \\        
\-2*tanh(x) + x*\-1 + 2*tanh (x)//*sech(x)
$$\left(x \left(2 \tanh^{2}{\left(x \right)} - 1\right) - 2 \tanh{\left(x \right)}\right) \operatorname{sech}{\left(x \right)}$$
Tercera derivada [src]
/           2        /           2   \        \        
\-3 + 6*tanh (x) - x*\-5 + 6*tanh (x)/*tanh(x)/*sech(x)
$$\left(- x \left(6 \tanh^{2}{\left(x \right)} - 5\right) \tanh{\left(x \right)} + 6 \tanh^{2}{\left(x \right)} - 3\right) \operatorname{sech}{\left(x \right)}$$
