# Write and compile math guide

33
###### Project Description

We have a list of math topics and we require a math professional to:

1. Write a short introduction/insight about each topic. There is no set word count required but what you write should fully explain the topic to a student.

2. Provide an example with calculation step in LATEX format.

3. Insert the data into our database using a web form which will be provided.

Here is what we are expecting from an example about the topic "Convert Percent Grade to Degree"

Percent grade and slope in degrees both indicate the amount that elevation changes over a certain distance, which determines how steep a hill or slope is. Percent grade denotes the percentage of change in the elevation--for example, if a hill rises 20 feet over a 100-foot distance, it has a 20 percent slope. The slope in degrees indicates the angle between the surface of a hill and level ground.

Example: $$20\% = \arctan(\frac{20}{100}) = \arctan(0.2) = [url removed, login to view]\mathrm{rad} \times \frac{180}{\pi} = [url removed, login to view]^{\circ}$$
