Mathematica

NOTE: On all Assessments, Mathematica may be used to rewrite any expression without showing any work.

Warnings:

  1. Be very careful with the syntax. Syntax is the set of rules on how to write computer code. Every software program has its own unique syntax. Some basic Mathematica syntax is located at: https://www.jjw3.com/Common_Mathematica_Code.html.

  2. Factor[ ] has at least one argument:

    1. The expression to be factored.
  3. For help on using the Factor[ ] function:

    1. In Mathematica, execute the code: ?Factor
    2. Click on near the bottom-left of output
    3. Click on local
    4. Read how to use the Factor[ ] function – you will be able to copy-paste code.
  4. Remember, correct Mathematica code will be all black except for variables.

  5. To execute code (including comment codes), press and hold the SHIFT key and press the ENTER key.

Python

NOTE: On all Assessments, Python may be used to rewrite any expression without showing any work.

Warnings:

  1. Be very careful with the syntax. Syntax is the set of rules on how to write computer code. Every software program has its own unique syntax. Some basic Python syntax is located at: https://www.jjw3.com/Common_Python_Code.html.
  2. Python requires ∗ for explicit multiplication, e.g., 8x is 8*x.
  3. Python requires ∗∗ for exponentiation, e.g., x3 is x**3.
  4. Remember to use parens ( and ) to group factors consisting of multiple terms.
  5. To execute code, press the “View the result” button: img

Distributive Property

xd(a0+a1x+a2x2++anxn)=a0xd+a1x1+d+a2x2+d++anxn+d

and

a0+a1x+a2x2++anxnxc=a0xc+a1x1c+a2x2c++anxnc

Distributive Property – Table Form

(a0+a1++an)(b0+b1++bn)=b0a0+b0a1+

Distributive Property – Method of Detached Coefficients

Example 01: (x32x21)(2x2+3x+5)

which corresponds to the polynomial 2x51x41x312x23x5.

Even and Odd Functions

Even Function: f(x)=f(x).

Even functions have reflectional symmetry over the y-axis.

Odd Function: f(x)=f(x).

Odd functions have rotational symmetry about the origin.

Use the embedded DESMOS file below:

Rational Exponents

xab=xab

Properties of Exponents

Absolute Value Functions

The absolute value function, |f(x)|, reflects any point below the x-axis over the x-axis, i.e., the absolute value function makes any negative y-value into a positive value.

Practice 01

  1. Rewrite using rational exponents: x23.

  2. Rewrite using rational exponents: (x2)75.

  3. Rewrite as a product of rational functions: ex+3.

  4. Rewrite as a product of rational functions: e2x.

  5. Factor completely over R2, if possible3: x2x6.

  6. Factor completely over R, if possible: x3+5x2+6x.

  7. Factor completely over R, if possible: x41.

  8. Factor completely over R, if possible: x33x2+2x6.

  9. Factor completely over R, if possible: x2+9.

  10. Expand: (x2+x1)(x2).

  11. Expand: (x22x1)(x2+x+4).

  12. Expand: (x2+3x2)2.

  13. Expand: (x2)3.

  14. Distribute: x23x+2x.

  15. Determine if the function is even, odd, or neither even nor odd: f(x)=x23x+2. Explain.

  16. Determine if the function is even, odd, or neither even nor odd: g(x)=tan1(x). Explain.

1 Terms are separated by addition or subtraction signs.
2 “over R” means using Real numbers only.
3 Expressions not factorable over R are called irreducible.
