By Robert D. Smith, John Peterson

Introductory Technical arithmetic, fifth variation presents present and functional vocational and technical math functions for today's refined alternate and technical paintings environments. every one unit can provide useful math options along step by step examples and difficulties drawn from a variety of occupations. The considerable examples and challenge units emphasize on-the-job purposes of math. improvements to the 5th variation comprise more advantageous algebra assurance, a brand new part on uncomplicated statistics, new fabric on conversions from metric to wide-spread structures of degree, and a bit that vitamins the fundamentals of operating with spreadsheets for graphing.

The Irrationals: A Story of the Numbers You Can't Count On

The traditional Greeks came across them, however it wasn't till the 19th century that irrational numbers have been effectively understood and conscientiously outlined, or even this day no longer all their mysteries were published. within the Irrationals, the 1st well known and finished booklet at the topic, Julian Havil tells the tale of irrational numbers and the mathematicians who've tackled their demanding situations, from antiquity to the twenty-first century.

In mathematical circles. Quadrants I, II (MAA 2003)

For a few years, famed arithmetic historian and grasp instructor Howard Eves accrued tales and anecdotes approximately arithmetic and mathematicians, accumulating them jointly in six Mathematical Circles books. millions of academics of arithmetic have learn those tales and anecdotes for his or her personal leisure and used them within the school room - so as to add leisure, to introduce a human point, to motivate the scholar, and to forge a few hyperlinks of cultural background.

Mathematics of Digital Images: Creation, Compression, Restoration, Recognition

This significant revision of the author's renowned publication nonetheless specializes in foundations and proofs, yet now shows a shift clear of Topology to likelihood and data thought (with Shannon's resource and channel encoding theorems) that are used all through. 3 important components for the electronic revolution are tackled (compression, recovery and recognition), developing not just what's actual, yet why, to facilitate schooling and study.

Mathe ist doof !? Weshalb ganz vernünftige Menschen manchmal an Mathematik verzweifeln

Viele Menschen haben den Seufzer "Mathe ist doof! " schon ausgestoßen. Sind denn alle diese Leute dumm oder "mathematisch unbegabt"? Wie kaum ein anderes Fach spaltet Mathematik die Geister: Mathematik ist schön, ästhetisch, wunderbar logisch und überaus nützlich - sagen die einen. Die anderen empfinden Mathematik als eine dröge Quälerei mit abstrakten Symbolen und undurchsichtigen Formeln, die guy irgendwie in der Schule durchstehen muss - und dann vergessen kann.

Multiplication by 1 does not change the value. The 1 used is in the form of a fraction that has an equal numerator and denominator. The value of a fraction is not changed by multiplying both the numerator and denominator by the same number.
