# Math Help - What does ¶ Mean!?

1. ## What does ¶ Mean!?

Hello
I Am very stumped.
I need to know what this symbol means.
¶?????
here it is in a equation
1 radian = 180 degrees / ¶
5 x 1 radian = 5 x 180 degrees / ¶
does anyoe know the value or meaning or name of this symbol?
If someone could help me that would be great thank you!!

2. Actually the symbol you're looking for is $\pi$. What you have is a symbol that marks the end of lines/paragraphs (such as in Microsoft Word).

Here's an entire article for you: Pi

3. Are you sure that the symbol means pi?
because this is the exact formula from the lesson in math 30 applied that I am working on rite now.
1 radian = 180 degrees / ¶

If it was pi? why wouldnt they just put pi... instead of confusing the out of me?

4. Yes it is pi and its symbol is $\pi$. What you've learned is a conversion between two different ways to express angles: 1 radian is equal to $\frac{180}{\pi} \: \text{degrees}$ or equivalently, 1 degree is equal to $\frac{\pi}{180^{\circ}}$.

With this new notation, we can see that, for example, $30^{\circ} = 30^{\circ} \cdot \frac{\pi}{180^{\circ}} = \frac{\pi}{6}$

When writing in terms of radians, usually we leave it unitless (if you want, add the unit 'rad' to the end).

5. Ok.... if you say so Ill give that a try
Thank-you very much.

! I really like that. Your comment.

That's just the beginning. Wait till you encounter other weird symbols that mathematicians use.
