To use Python's trig functions, we need to introduce a concept:importing modules. In Python, there are many operations built into the language when the REPL or a Jupyter notebook starts. These operations include+,-,*,/like we saw in the previous post. However, not all functions will work...
When I first tried using vi I thought that you could not have a more obscure and difficult-to-use text editor, but I found that after memorising half-a-dozen commands that it was really quite simple to use. And, quite powerful. For example, you can do something like “find all lines ...
For the runtime comparison between AI Pontryagin and the AGM, we use the command timeit in python. In accordance with ref. 41, the energy regularization parameter β of the AGM is set to 10−7 (see the SI for a more detailed analysis of the AGM control performance on β). Initially,...

and export it to file and then import it again as an interpolation function, perhaps in a separate model. This interpolation function can then be used in a variety of ways, as we will explain later. Alternatively, you can use external software to generate the data by means of inverse FFT...
textures-auto-power-2 1 allows us to use texture sizes that are not a power of two if the system supports it. This comes in handy when doing SSAO and other screen/window sized related techniques since the screen/window size is usually not a power of two. textures-power-2 down downsizes...

In MS Excel, what does it mean when a cell is populated with hashtags? Use Python for the following. You know that the Taylor Series for sin x is sum_k=0 ^infty (-1)^k x^2k+1 (2k+1)! . We can truncate the series to get an approximation for sin x as follows: sin x = ...
