# pydrawer 📐 The Python package for visualizing curves and linear transformations in a super simple way.

## ✏️ Installation

Install pydrawer package with pip:

``````\$ pip install pydrawer
``````

or clone the repository:

``````\$ git clone https://github.com/dylannalex/pydrawer.git
``````

## ✏️ Usage

### 📌 Drawing curves

To start drawing curves you need to create a `GraphingCalculator` object:

``````from pydrawer import GraphingCalculator

graphing_calculator = GraphingCalculator()
``````

pydrawer let you draw parametrized curves and mathematical functions. Lets create and draw the square root of x function for this example:

``````def square_root(x):
return x ** (1 / 2)

graphing_calculator.draw(square_root, (0, 25))  # We want to draw the function from x = 0 to x = 25
``````

You can also accomplish the same result by defining the square root of x as a parameterized function:

``````def square_root(t):
return t, t ** (1 / 2)

graphing_calculator.draw(square_root, (0, 25))  # We want to draw the curve from t = 0 to t = 25
``````

### 📌 Linear transformations

pydrawer provides a `curves` module which contains functions for modifying curves with linear transformations.

``````from pydrawer import curves
``````

#### 📍 `curves.transform_curve()`

This function let you apply a linear transformation (specified as a matrix) to a parametrized curve. `curves.transform_curve()` returns the transformed curve.

Parameters:

• curve: parametrized curve
• matrix: linear transformation's matrix

The matrix is a tuple of tuples (or list of lists) which has the same structure as numpy arrays. A matrix
[ a b ]
[ c d ]
should be defined as:

``````matrix = ((a,b), (c,d))
``````

Example:

``````matrix = ((1, 0), (0, -2))
graphing_calculator.draw(curves.transform_curve(square_root, matrix), (0, 25))
``````

#### 📍 `curves.rotate_curve()`

Rotates a curve anticlockwise by the given angle.

Parameters:

• curve: parametrized curve
Example:
``````angle = pi / 4  # 90 degrees
graphing_calculator.draw(curves.rotate_curve(square_root, angle), (0, 25))
``````

#### 📍 `curves.scale_curve()`

Scales the given curve by the given scalar.

Parameters:

• curve: parametrized curve
• scalar: scalar for scaling the curve
Example:
``````scalar = 2  # The function is going to be twice as bigger
graphing_calculator.draw(curves.scale_curve(square_root, 2), (0, 25))
``````
