Useful Formulas for Exploring the Night Sky Randy Culp Introduction Objective lens collects light and focuses it to a point Eyepiece catches the light as it diverges away from the focal point and bends it back to parallel rays so your eye can refocus it to a point . 4 Di64256erence Equations At this point almost all of our sequences have had explicit formulas for their terms That is we have looked mainly at sequences for which we could write the th term as for some known function For example if 1 3 then i Equations of the form dy dx are called Riccati equa tions If is kno wn particular solution to Ricatti equation then the substitution will transform the Riccati equation in to Bernoulli equation a If then what do and equal in terms of and Solution e Ax where is vector is a linear function of ie By where is then is a linear function of and By BA so matrix multiplication corresponds to composition of linear functions ie linear functions of linear functions of some variables Linear Equations orgpublicinformationatefaqsgammaandexposurehtml It is a very good white paper by George Chabot CHP PHD that takes you from electric charge produced in the air by the photons to a usable equation and also explains where the simplified rule of thumb Rh . An appeal by IUA and UNESCO: . “… the citizens of the world rediscover their place in the Universe through the day- and night-time sky observation, and thereby engage a personal sense of wonder and discovery… . Summary. Independent. The equations of a linear system are . independent. if . none. of the equations can be derived algebraically from the others. . Independence. When the equations are independent, each equation contains new information about the variables, and removing any of the equations increases the size of the solution set. . I can identify the products and reactants in a chemical reaction.. I can state the law of conservation of matter.. I can determine the number of each atom in a compound based on subscripts and coefficients.. By: Morgan Shade . Absolute Value. The number’s distance away from zero. Can’t be a negative number. Examples:. │3│= 3. │-10│= 10. │0│= 0. Absolute Value Equations. Isolate the Absolute Value. If you read from left to right . 10 . “is greater than “ . 5. . X.
