 si y =3x+1(6x+5)2    la derivada es:si\ y\ =\frac{3x+1}{\left(6x+5\right)^2}\ \ \ \ la\ derivada\ es:  

 dydx= (16x)(6x+5)3\frac{\text{d}y}{\text{d}x}=-\ \frac{\left(1-6x\right)}{\left(6x+5\right)^3}  

 dydx= 16x(6x+5)3\frac{\text{d}y}{\text{d}x}=\ \frac{1-6x}{\left(6x+5\right)^3}  

 dydx= 13x(6x+5)3\frac{\text{d}y}{\text{d}x}=\ \frac{1-3x}{\left(6x+5\right)^3}

 f(x)=x2e3x   Calcular d2ydx2f\left(x\right)=x^2e^{3x\ \ }\ Calcular\ \frac{\text{d}^2y}{\text{d}x^2}  

 d2ydx2=e3x (9x210x2)\frac{\text{d}^2y}{\text{d}x^2}=e^{3x}\ \left(9x^2-10x-2\right)  

 d2ydx2=3e3x(9x2+12x+2)\frac{\text{d}^2y}{\text{d}x^2}=3e^{3x}\left(9x^2+12x+2\right)  

 d2ydx2=(9x2+12x+2)e3x\frac{\text{d}^2y}{\text{d}x^2}=\left(9x^2+12x+2\right)e^{3x}
