31	Trigonometry: Applications of Laws of Sines and Cosines Su, Yen-hao 02 July 2010 (has links) Chapter 1 presents the definitions and basic properties of trigonometric functions including: Sum Identities, Difference Identities, Product-Sum Identities and Sum-Product Identities. These formulas provide effective tools to solve the problems in trigonometry. Chapter 2 handles the most important two theorems in trigonometry: The laws of sines and cosines and show how they can be applied to derive many well known theorems including: Ptolemy¡¦s theorem, Euler Triangle Formula, Ceva¡¦s theorem, Menelaus¡¦s Theorem, Parallelogram Law, Stewart¡¦s theorem and Brahmagupta¡¦s Formula. Moreover, the formulas of computing a triangle area like Heron¡¦s formula and Pick¡¦s theorem are also discussed. Chapter 3 deals with the method of superposition, inverse trigonometric functions, polar forms and De Moivre¡¦s Theorem. Sum Identities Difference Identities Double-Angle Identities Product-Sum Identities Sum-Product Identities Ceva's Theorem Menelaus's Theorem Ptolemy's Theorem Law of Sines Law of Cosine Euler Triangle Formula Inverse Trigonometric Functions Euler's Formula De Moivre's Theorem Pick's Theorem Weitzenbock's Inequality Heron' Formula Polar Coordinates Angle Bisector Formula Brahmagupta's Formula Median Formula Stewart's Theorem Parallelogram Law

33	Analýza fotografických záznamů nerybí kořisti v potravě vybraných druhů rybožravých ptáků / Analysis of photo-records of non-fish prey in the diet of selected species of fish-eating birds Mach, Jakub January 2021 (has links) Piscivorous birds are often blamed for causing significant damage to fish stocks. Various methods are used to determine the composition of their food, each of them has limits in its ability to determine the complete food spectrum. This work maps the complete food composition of 14 species of fish-eating birds with a method that is not commonly used. Method used in this work uses analysis of publicly available photos on Google.com. In addition to the complete composition of the food, the species composition of the non-fish part of the prey was also determined, and in the case of the Great Cormorant (Phalacrocorax carbo), also the length of the fishes it catches. The aim of this work is to reveal the usability of this method for these purposes. A total of 2350 retrieved photographs were analyzed. The results obtained by photo analysis are in all cases compared with data in the available literature. For representatives of heron birds (Ardeidae), the analysis of photographs provided good information on the food spectrum of individual birds and on the qualitative composition of the non-fish component. It also provided relatively good information on the diet of the White-tailed Eagle (Haliaeetus albicilla), but the bird part of the prey was slightly underestimated. In the diet of the Great Crested Grebe...
