Introduction

+

+
For the smooth running of this evaluation, please respect the following rules
- Remain polite, kind, respectful and constructive whatever happens during
this conversation. It's a matter of confidence between you and the
42 community.

- Highlight the possible problems you met with the work you're presented to
the person or the group you're grading, and take the time to talk about and
discuss those.

- Accept the fact that the exam subject or required functions might give place
to different interpretations. Remain open to your discussion partner's
perspective (are they right or wrong ?) and grade them as fairly as possible.
42's teaching methods can make sense only if peer-assessment is
seriously made.
+

+
+
+

Guidelines

+

+
REMEMBER: you must only evaluate what's in the student's repo. You have to make
a "git clone" of the repo and evaluate what's in it. If the assessor has not
yet made this project, he will have to read the subject in its entirety before
starting this evaluation.

Foreword

+

+
+

Preliminary instructions

+

+

First, check the following elements:

+ +
    +
  • There is a turn-in (in the git repository)
    • +
  • No cheating. Students must be able to explain their code.
    • +
  • If the program is written in a compilable language, there is a Makefile +with the rules all, re, and clean, at least.
    • +
  • Mathematic libraries are not allowed in this project. They cannot be used +to calculate the delta root or any second degree equation. You should +check which calculation method the student used and whether they master +it.
    • +
  • If one of these elements is not respected, evaluation stops. Use the +accurate flag. Still, you're invited to keep discussing the subject, but +you won't use the grading system.

First section

+

Mandatory part +

+
+

Presence of a reduced equation

+

+

The program takes an equation in account or waits for it on the standard
+entry and displays the same equation in its reduced form afterwards. Is
+it the right one ?

+ +

+
+ + +
+ + + + +
+
+

Reduced equation form

+

+

The reduced equation shows the factors until the non null last one, only
+once, and either side of the equation is null.

+ +

+
+ + +
+ + + + +
+
+

Entry management

+

+

Try several entries that have a correct format but might have been ill
+managed (zero or negative or non whole coefficient...). How well does the
+program manage them? (no crash, no calculation error, no infinite loop...)
+IMPORTANT NOTICE: if the answer is NO to either question, the evaluation
+stops.

+ +

+
+ + +
+ + + + +
+
+

0 degree equation after reduction

+

+

Enter a possible equation ("5 * X^0 = 5 * X^0", for instance). Does the
+program tell you that any real number is a solution? Enter an impossible
+equation ("4 * X^0 = 8 * X^0", for instance)? Does the program tell you
+there is no solution?

+ +

+
+ + +
+ + + + +
+
+

First degree equation after reduction

+

+

Enter a fist degree equation ("5 * X^0 = 4 * X^0 + 7 * X^1", for instance).
+Does the program show the solution to the equation?

+ +

The program is expected to display:

+ +

5 = 4 + 7X ⇒ X = 1/7 ≈ 0.142857

+ +

(Note: the reduced form may have a different development,
+but the final result must remain the same.)

+ +

Run several tests.

+ +

+
+ + +
+ + + + +
+
+

Second degree equation after reduction - Strictly positive discriminant

+

+

Enter a second degree equation with a strictly positive discriminant
+("5 * X^0 + 13 * X^1 + 3 * X^2 = 1 * X^0 + 1 * X^1", for instance).

+ +

Does the program show it has a strictly positive discriminant?

+ +

Does it show two solutions?

+ +

Are they correct? (here's an example of a possible solution)

+ +

X1 = (-12.0 + sqrt(96.0)) / (2 * 3.0)
+X1 = -0.36700683813442847

+ +

X2 = (-12.0 - sqrt(96.0)) / (2 * 3.0)
+X2 = -3.632993161865572

+ +

(Note: the reduced form may have a different development,
+but the final result must remain the same.)

+ +

Run several tests.

+ +

+
+ + +
+ + + + +
+
+

Second degree equation after reduction - Zero discriminant

+

+

Enter a second degree equation with a discriminant equalling O.

+ +

("6 * X^0 + 11 * X^1 + 5 * X^2 = 1 * X^0 + 1 * X^1", for instance).

+ +

Does the program show it has a 0 discriminant?

+ +

Does it show a single solution?

+ +

Is it the correct one? (here's an example of a possible solution)

+ +

X0 = -10.0 / (2 * 5.0)
+X0 = -1.0

+ +

Run several tests.

+ +

+
+ + +
+ + + + +
+
+

Second degree equation after reduction - Strictly negative discriminant

+

+

Enter a second degree equation with a strictly negative discriminant
+("5 * X^0 + 3 * X^1 + 3 * X^2 = 1 * X^0 + 0 * X^1", for instance).

+ +

Does the program show it has a strictly negative discriminant?

+ +

Does it show two complex solution?

+ +

Are they correct? Run several tests.

+ +

The result should of course show like this: α + β*i.

+ +

(here's an example of a possible solution)

+ +

Discriminant is strictly negative, the two solutions are complex:
+real_part: -3.0 / (2 * 3.0)
+imag_part: sqrt(39.0 / (2 * 3.0))
+-0.5 + 1.0408330009701328 * i
+-0.5 - 1.0408330009701328 * i

+ +

+
+ + +
+ + + + +
+
+

Third or more degree equation after reduction

+

+

Enter a third or higher degree equation. The program should refuse to solve
+the equation first. If the program solves it, you can give a score and
+show respect... as long as it doesn't crash. If the reduced equation happens
+to be a second or lower degree equation, the program should be able to
+solve it properly.

+ +

+
+ + +
+ + + + +
+
+
+
+
+
+

Bonus

+

+Bonus part +

+
+

Managing a free form entry

+

+

Can the program manage a free form entry? * A single coefficient ("4") is
+considered a factor of X^0. * A single X is considered having a
+coefficient 1 an exponent 1. * An absent exponent ("4 * X") is considered
+as equalling 1. * An absent coefficient ("X^6") is considered as equalling

+ +
    +
  1. * Exponents can appear in arbitrary or repeated order.
    2. +
+ +

+
+ + +
+ + + + +
+
+

Second bonus

+

+

Error management in the entry (vocabulary and syntax).
+Displaying results as irreducible fractions if appropriate. Displaying
+intermediate steps. Etc...

+ +

+
+ + +
Rate it from 0 (failed) through 5 (excellent)
+
+
