plot homework maximum minimum

(a) Plot the graph of  
                       sin(x)*exp( -x^2)
 for x in the interval [-2,2]. 
(b) Find to 10 decimal digits the maximum and minimum values of 
                         sin(x)*exp( -x^2)
 for x in [-2,2] AND find the corresponding values of x. [So if the maximum occurs at x=a, you should also compute sin(x)*exp( -x^2)   both to 10 digits. Similarly for the minimum. Using unapply to make the expression into a function will be useful here.]  

So far I have this for a

> j := exp(-x^2)*sin(x);

> plot(j, x = -2 .. 2);
