 1.)  Give an example of a linear differential equation:

~~~$y' + y = 0$  or $sin(t)y y' + t^{1 \over 2} y = ln(t)/e^t$ or ...

 2.)  Give an example of a non-linear differential equation:

~~~$y' y = 0 $ or ....

3.)  From section 1.4, name one mathematician who studied differential equations OR one application (but not related to gravity) of
differential equations.


~~~Newton or mechanics or ...


4.)  Circle T for True or F for False:


4a.) Numerical approximations for solutions to differential equations are often needed as the solutions 
to most differential equations cannot be expressed algebraically.

4b.)  If a computer is used to find a numerical approximation to a differential 
equation, then we know the equation has at least one solution.
