slope-field
|
|
===========
|
|
|
|
I was studying [this course on Integration](https://www.edx.org/course/calculus-1b-integration-mitx-18-01-2x) when I encountered
|
|
slope fields and I found them interesting!
|
|
|
|
So I thought I would give it a shot and try to write a program to draw slope fields myself!
|
|
In order to read a mathematical function definition from input, I wrote [mathexpr](/mdibaiee/mathexpr).
|
|
|
|
Get Started
|
|
-----------
|
|
If you haven't already, install [Haskell Platform](https://www.haskell.org/platform/).
|
|
|
|
```
|
|
git clone https://github.com/mdibaiee/slope-field
|
|
cd slope-field
|
|
stack install
|
|
slope-field
|
|
```
|
|
Examples
|
|
--------
|
|
Parameters:
|
|
- dy/dx: derivative of the function you are trying to visualize
|
|
- range: range of numbers to draw
|
|
- estimation size: size of `deltax` which is used to draw the slope corresponding to a small point, `0.03` is usually a good number, but you might want to try out larger numbers to get a more detailed picture on some examples
|
|
```
|
|
dy/dx =
|
|
x + y
|
|
range - format: (lower, upper):
|
|
(-10, 10)
|
|
estimation size:
|
|
0.03
|
|
```
|
|
|
|
|
|
|
|
```
|
|
dy/dx =
|
|
x * y
|
|
range - format: (lower, upper):
|
|
(-10, 10)
|
|
estimation size:
|
|
0.03
|
|
```
|
|
|
|
|
|
|
|
```
|
|
dy/dx =
|
|
-y
|
|
range - format: (lower, upper):
|
|
(-10, 10)
|
|
estimation size:
|
|
0.03
|
|
```
|
|
|
|
|
|
|
|
```
|
|
dy/dx =
|
|
y/x
|
|
range - format: (lower, upper):
|
|
(-20, 20)
|
|
estimation size:
|
|
0.1
|
|
