Chemistry 3730 assignment 1 solutions

Maple input and output is offset from the main text by horizontal lines.

1. To get the exact value, just integrate:
   

   > int(exp(-x^2),x=Pi..8);

   

   
   

   To get the floating-point value, use evalf:
   

   > evalf(");

   

   
   

2. 
   

   > solve(x^3+3*x^2+8*x+6=0,x);

   

   
   

   Maple uses I for the complex unit (what most textbooks call i, i.e. the number such that ) so the last two solutions are complex.
