tan 1.107 = tan 63.435º = 2 The arctangent of 2 is equal to the inverse tangent function of 2, which is equal to 1.107 radians or 63.435 degrees: arctan 2 = tan-12 = 1.107 rad = 63.435º
What is in physics? What is the amplitude of y = 6 \sin x? What is the amplitude of y = 3sin(2x - 1) + 4? What is the amplitude of y = 2tan((1/2x)) - 3? What is the amplitude for y = -3tan(4x)? What is the amplitude for y = 2sec((1/2)x)?
Theoretical Physics: Lopez has suggested that far-reaching concepts such as string theory constitute a kind of mathematical pataphor, insofar as these concepts correspond to the 'pataphysical notion of "supposition built on supposition." As string theory is speculation based on ideas that are ...
Santa Claushas ample time to get nice and tan. At the North Pole, thesun riseson the spring equinox in March. Then it lingers in the sky — without setting — until September's autumn equinox comes along. Between those dates, the big old star reaches its highest point in the polar sky...
notation, i.e.,\({[X]}=\log {X_{\mathrm{star}}} -\log {X_\odot }\)for any abundance quantity X, and\(\log {\epsilon (X)} = \log {N_{{X}}/N_{\mathrm{H}}} + 12.0\)for absolute number density abundances. For helium, we use Y, that is the fraction of He in ...
Quantum Physics is a pleasure to read and, almost inevitably, re-read. Except for those already working in the world of photonics and quantum optics, everyone reading this will learn from its detailed description and style of expression. Ideas are sequential but not chronological; the conceptual ...
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) taken up by plant roots to CO2 to producecarbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water is "oxidized," or loses electrons. Oxygen is produced along with carbohydrates....
algorithms will scale up effectively to larger quantum systems, and in helping determine which applications have the greatest potential for advantage. Even today, research groups in fields like condensed-matter physics can use the current generation of 100+ qubit systems to explore new problem scales...
