Give a short answer for the following questions (you might need to do some search and/or consult your textbook).

 (a) A well-versed programmer wrote a code to solve Laplace partial differential equation using C++, then wrote the same code using MATLAB. Which version is expected to be faster? 

(b) In your graduation project, you needed to solve a linear first order differential equation. In MACT 2141 you learned how to solve it analytically using an integrating factor. In ENGR 3202 (later this semester) you learn how to solve use it numerically using Runge-Kutta method. In your thesis report, which solution method you will present and why? 

(c) How many significant digits in 0.0399?

 (d) There are only 4 significant digits in the number 335000. Write it in the scientific notation. 

(e) You have a 64-bit laptop. You wrote a MATLAB code employing double-precision (default in MATLAB!). There is a key advantage and two drawbacks, what are they?
