1. What's the result of these divisions in Maxima?

   Maxima usually tries to calculate quantities exactly rather than approximating them by decimal numbers. It does this by manipulating the symbols in the expression according to the rules of mathematics. This is sometimes known as symbolic computation.

2. How to assign a variable in Maxima?

   a: 5

3. How to plot a function f(x):=x^5-3*x^2+4;?

   wxplot2d(f(x), [x, -2, 2]);

4. Name 2 ways to check whether 2 equations are the same.

   difference between them should be zero or a rougher check - plot them As with variables, once you have defined a function in Maxima it is remembered by the system for the rest of your session, unless you remove it using the kill command

5. How can you enter ex in Maxima?

   %e^x exp(x)

6. What do ' vs '' do in Maxima? ' ''

   ' - prevents evaluation. '' - causes evaluation when evaluation is otherwise suppressed. ...such as in function definitions, lambda expressions, and expressions quoted by single quote '. The quote-quote operator is applied by the input parser; it is not stored as part of a parsed input expression. The quote-quote operator is always applied as soon as it is parsed. Maxima distinguishes between operators which are "nouns" and operators which are "verbs". A verb is an operator which can be execute…

7. How would you find numerical solutions to where f(x) intersects the x-axis?

   solutions: solve(f(x) = 0)sol1: rhs(solutions[1]); float(sol1);
