Due to the similarity between sine and cosine functions, transformations of y = cos (x) to y = a cos (n x − b) + c have the same effects as transformations of y = sin (x) to y = a sin (n x − b) + c.

Graphs of Logarithmic Functions The logarithmic function is the inverse function to the exponential function. The logarithmic function is defined as f (x) = log a (x) where a, x ∈ R + and a ≠ 1. The ...

The Handbook of Mathematical Functions by Milton Abramovich and Irene Stegun is the one book I would wish to have on a desert island. Unlike a novel, it withstands infinities of rereadings. Its ...

The problem of efficient, interactive foreground/background segmentation in still images is of great practical importance in image editing. Classical image segmentation tools use either texture ...
