slope-field

I was studying this course on Integration 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.

Get Started

If you haven't already, install Haskell 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): 
(-10, 10)
estimation size: 
0.1
