Question 1208877
<pre>

{{{matrix(1,3,y,""="",matrix(2,1,"",e^(-x^2)))}}}

To take the derivative, copy it over then multiply by the derivative 
of the exponent: 

{{{matrix(1,3,"y'",""="",matrix(2,1,"",e^(-x^2))*(-2x))}}} 

First times the derivative of the second plus the second times the
derivative of the first:

{{{matrix(1,3,"y''",""="",matrix(2,1,"",e^(-x^2))*(-2)+(-2x^"")*(e^(-x^2))*(-2x)))}}} 

Substitute x = 0

{{{matrix(1,3,"y''(0)",""="",matrix(2,1,"",e^(-(0)^2))*(-2)+(-2(0))*(e^(-(0)^2))*(-2(0))))}}}

{{{matrix(1,3,"y''(0)",""="",1*(-2)+(0)*(1)*(0))}}}

{{{matrix(1,3,"y''(0)",""="",-2)}}}
