## anonymous 3 years ago What or how do you code or show a test case in python?

1. eSpeX

A test case for what?

2. anonymous

Never mind me. Tired and not thinking right. I read further in the assignment and basically figured it out. Though i do have a separate question you could me out with. In the assignments for 6.189 whenever they have a maths question there is a symbol that i just cannot find what it means. It looks like a / or \ but slightly curved. What does it mean?

3. e.mccormick

$$\int$$ ? Integral.

4. eSpeX

Which of the .189 problems uses integrals?

5. anonymous

Don't know. It's in Homework 1. Ex 1.4 part 1 question/example 2 $7 * \frac{ 1 }{ 2}$ and they are around the 1.

6. eSpeX

( )

7. eSpeX

Parenthesis, used for grouping and enforcing order of operations.

8. eSpeX

$$7*(\frac{1}{2})$$ tells you to do the 1/2 first and then multiply by 7.

9. anonymous

Its not a parentheses and its only over the 1.

10. anonymous

Theres another in Homework 2 Ex 2.3 question 2 next to angle_test.

11. e.mccormick

Yah, but with \left( \right to make them the same size as the fraction: $$7*\left(\cfrac{1}{2}\right)$$

12. e.mccormick

Which version of the Acrobat Reader do you have?

13. eSpeX

My page looks the same as the one @e.mccormick posted, I'm not seeing a symbol above the 1.

14. anonymous

15. eSpeX

Part of your parenthesis is missing.

16. e.mccormick

Yah, that is the new, messed up browser version of the reader. If never works right and I wish they would just remove it. use the download button on the upper left, get a real copy of the file, and open it in regular Acrobat Reader and it is all fine.

17. anonymous

Wow after all of that. I have literally spent the last hour and a half trying to track down what the symbol means. If I save the pdf and then view it its right. Damn my life to hell and back LMAO.

18. eSpeX

:)

19. e.mccormick
