... work with. The examples below show how to round off numbers and then how to estimate your answer. EXAMPLE # 1 Round 3274 to the nearest ten. 3274 becomes 3270 The '7' is in the tens place. If the number behind the '7' is a 5 or larger, the '7' becomes an '8'. Otherwise it stays the same as it did in ...

... 19) Suppose the graphs of f(x)= x^2 and g(x)=2^x are drawn on a coordinate grid where the unit of measurement is 1 inch. Show that at a distance of 2 feet to the right of the origin, the height of the graph of f is 48ft but the height of the graph of g is about 265mi. (Please check that your functio ...

... Uncountability of R Cantor’s Diabolical Diagonal GENERALIZE: To construct a number not on the list “revil”, let ri,j be the j ’th decimal digit in the fractional part of ri. Define the digits of revil by the following rule: The j ’th digit of revil is 5 if ri,j 5. Otherwise the j’ ’th digit is se ...

Radio Propagation
... readily done by phase self-cal at frequencies of 10 GHz and lower. At higher frequencies the influence of water vapour and clouds and rain make such corrections increasingly difficult. • Correction for propagation in the Earth’s ionosphere is necessary at frequencies below about 400 MHz. As the freq ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
