246. Current weather for the Moab Area.
The transformations you have seen in the past can also be used to move and resize graphs of functions. We will be examining the following changes to f (x): - f (x), f (-x), f (x) + k, f (x + k), kf (x), f (kx) reflections translations dilations. Reflections of Functions: -f (x) and f (-x)
The Fourier Transform. The Fourier Transform and its inverse relate pairs of functions via the two formulas. My goal here again isn't a rigorous derivation of these guys (this can be found all over the internet), but instead an explanation of why exactly they take this form, and what they do.
