Image of Composite FunctionsAnalyzes the image sets of composite functions on [1, +∞], deducing the final image set as [√2/2, 1) closed left, open right.
The Sampling TheoremExplores the sampling theorem, basis expansion, Nyquist frequency, and signal representation.
The Sampling TheoremCovers the sampling theorem, impulse train sampling, bandlimited signals, and the Nyquist rate.
Approximation: PolynomialCovers orders of magnitude in physics and polynomial approximation for simplifying complex functions.
