Best Platforms for Posting Word Problems on Physics Forums

[harpazo]

Which PF is best fitted for posting word problems?

Thanks

 

[fresh_42]

In the homework forums. But be aware that language is usually not unique so that misunderstandings can happen. Formulas are more precise.

Formulas are more precise.

@harpazo -- Please be sure to read through the "LaTeX Guide" link below the Edit window at the left. We strongly prefer that you post any math equations using LaTeX, since it is much easier to read and to quote and correct. Thank you.

I do not plan to post equations. Most of my threads will consist of word problems.

Most of my threads will be word problems not equations or shapes.

Homework Help does not have a specific window for word problems at the high school and undergraduate college level. Posting algebra applications in the precalculus and calculus forums is not placing material in the right place.

That's nonsense. Math is used to solve word problems. As we explained to a new member recently, the keys to solving word problems is to figure out good variables to define and then figure out what equations to write to put the word problem into solvable form.

HH/Pre-calculus Math is the right forum.

A word problem is math and words together to form a statement.

Sample:

If Lisa has two boxes of 20 Maranatha albums, how many albums does she have in all?

Learning LaTex will take some time.

I made up that problem to provide an example.

If it takes three boxes of beer a day for the constructors to build the house in seven days, how much beer would it take them to build it in six?

Exactly.

The basics are pretty easy, especially for pre-calculus problems. The advantages are clean fractions, exponents, clear grouping of terms, etc.

Also, you can "Reply" to a post that has LaTeX in it to see how it is formatted (you don't actually click "Post reply", you just use the "Reply" link to get the post's text into the Edit window where you can see the math formatting). You may need to toggle the "BB Code" icon to see the raw LaTeX though (use the "[ ]" icon to the upper right of the Edit window).

For instance, you can click "Reply" on my reply here to se how I did this:

$$I_d = I_s (e^{(\frac{qV_d}{nkT})}-1)$$
Or you can make the LaTeX in-line by using a double-# instead of double-$ like this $F_{max} = m a_{max}$

You hire carpenters to work on your home renovation. Their work day starts at 07:00 and they stop at 15:00. The carpenters work 25% faster if they know they will get beer in the afternoon, but after beer they work at only 90% of their normal pace. What time should you bring out the beer?

That one, goes in the HH / calculus section.

EDIT: Sorry, file that one in the poorly written problem bin.

At first, I will be using linear equations like
2x + 4 = 50 or x + 6 = 4x - 7, etc. LaTex is not needed for linear equations.

´Sure, but you only need to write ##2x+4=50## or ##x+6=4x-7## instead

Really? Let me try that.
