1. ## Cheating?

Hey everybody its about 2/3 the way trough summer break and I am taking 2 math classes next year. I just had a question. If i make a calculator for the functions we learn, is that cheating, because technically I know the function inside and out if I can make a calculator for it. If you think otherwise or just want to put in your thoughts please comment below.

2. Err... no, but if you may be missing out on good practice, especially if you cannot take this calculator with you to the exam hall.

3. Your teacher is the final authority on that matter, won't you think? Ask him. You may be surprised with the answer...

4. ok... these are both true, Ill ask him/her.

5. They can be a good tool for learning, actually. It's great to use them to test ideas instead of doing it by hand. You save lots and lots and lots of time that would otherwise be wasted.
So when you know your idea works, you could easily get more practice solving the problems by hand later.
Again, however, it's a double-edged sword. Because your cannot use them on your exams (usually).

That said, I do like to use calculators and tools for doing math problems. Because I can test ideas and approaches quickly and learn how to best approach these problems. But I make sure to calculate them by hand as well, because otherwise you will never learn anything.

6. If you know enough about the problems in class to make your own calculator, why haven't you tested out of class and done something more challenging?

7. Because, my high school is dumb
and like they said, I may have made it but its still a calculator,

after school last year I took up C programming, a week later I had a fully functional quadratic formula calculator with full explimation on how it gets that answer.
I even took it to Pearson - Math and I got every answer (concerning what the calculator solves) right.
If you want it I attached a .c file.

EDIT:
it used to work. probably an easy fix though
EDIT:
I thought it was broken because I tried running it when it was running and got an error message. LOL. I works though

8. ... what's the circular recursion for?

9. Because I didn't like having to open it then it gives me an answer then it closes then I have to open it up again, I just wanted to open it and get all the answers that I wanted then close it

10. Indentation needs improvement.
main must have a return type.
And don't recursively call main. Use a loop.

11. Ok thanks I will, Its not that important of a project but I will do that on my other projects.

Thanks.

12. I wish I knew how to program (and owned a computer) when I went to school. All the wasted time on math exercises...

But then, it is possible to make the computer do math exercises without any particular understanding of the math behind it. When I need a GCD algorithm, I just copy it off Wikipedia. I don't need to understand the math behind it, just how to translate the pseudocode into a programming language.

Recently I had to solve triangles. Initially I thought there were not going to be many, and I reinvented everything from the definitions of trigonometric functions for each particular case. Then it occurred to me that a Python module would be much simpler. All it took was to implement formulas from a textbook.

13. Are you referring to the graphing calculators? I know pretty much every time I've used one in an exam the teacher clears them out for cheaters. If you're asking the C board and not your teacher, it's probably not going to fly.

14. That pretty much depends on what level you're at. Usually. And other factors.
But sometimes they're allowed. You just need to make sure you know the rules.

You are in doubt about your teacher's gender?

[EDIT] I think women are more conservative on these matters. So the answer probably will be no.
