If you are absolutely stuck, //talk// to a fellow student, the teaching assistant, or the instructor, and get hints for how to proceed. But **do not** copy someone else's solved problem. |
| **Problem 1:** Given two numeric variables $x$ and $y$, write a Matlab expression that evaluates to true (1) if $x$ and $y$ have opposite signs and false (0) otherwise. By opposite signs, I mean one is positive and one is negative. Test the expression by evaluating it with the following pairs of numbers (x,y) = (-5, 4), (5,4), (5,-4), (0,-2), and (3,0). | **Problem 1:** Given two numeric variables $x$ and $y$, write a Matlab expression that evaluates to true (1) if $x$ and $y$ have opposite signs and false (0) otherwise.
