Sample Learning Goals


For Teachers

In the real numbers, we can express a relationship between two sets of numbers by mapping elements from one set to elements in another. We call this mapping a function.

To visualize this, we can plot out a graph of y against x, where y = f(x).

However, this is not possible with complex numbers, which are represented with a 2-dimensional plane. Thus, we map a complex number from one Argand plane to another Argand plane. By seeing how each function transforms a square array of points (red to blue) and the unit circle (black), we can reveal some very interesting properties of how complex numbers behave under a function.

The available functions are as follows:
- Exponential (w = e^z)
- Sine (w = sin(z))
- Cosine (w = cos(z))
- Tangent (w = tan(z))
- Logarithmic (w = ln(z))
- Power (w = z^n)
