205 How could you use Descartes’ rule and the Fundamental Theorem of Algebra to predict the number of complex roots to a polynomial as well as find the number of possible positive and negative real roots to a polynomial? | Descartes rule is really helpful because it eliminates the long list of possible rational roots and you can tell how many positives or negatives roots you will have. Fundamental Theorem of Algebra finds the maximum number of zeros which includes real and complex numbers

didn’t leave much time for his love of math. Since math was just his hobby‚ he never wanted any of his work to be published. When he did publish his work‚ it was always anonymously. Fermat would state theorems‚ but always neglected the proofs. For example‚ his most famous work‚ ‘Fermat’s Last Theorem‚’ didn’t include a proof until when Andrew J. Wiles provided the first in 1993. He made many contributions in the field of mathematics. For example‚ he is considered as one of the ‘fathers’ of analytic

CALCULUS Calculus is the study of change which focuses on limits‚ functions‚ derivaties‚ integrals‚ and infinite series. There are two main branches of calculus: differential calculus and integral calculus‚ which are connected by the fundamental theorem of calculus. It was discovered by two different men in the seventeenth century. Gottfried Wilhelm Leibniz – a self taught German mathematician – and Isaac Newton - an English scientist - both developed calculus in the 1680s. Calculus is used in a

MODIGLIANI-MILLER THEOREM Courtney A. Hopley February‚ 2003 Economics Major Despite the fact that the Tax Reform Act of 1986 was the most sweeping tax reform effort in recent US history‚ critics are concerned that the act could have worsened the distortion of corporate financing decisions by failing to address the unequal treatment of debt and equity finance. Two conflicting theories‚ the traditional theory of corporate finance and the Modigliani-Miller Theorem‚ make different predictions

Partial Sums of the Riemann Zeta Function Carlos Villeda December 4th‚ 2010 Chapter 1 Introduction 1.1 Riemann Zeta Function In 1859‚ Bernard Riemann published his paper “On The Number of Primes Less Than a Given Magnitude”‚ in which he defined a complex variable function which is now called the Riemann Zeta Function(RZF). The function is defined as: ζ(s) = Σ 1 ns (1.1) Where n ranges over the positive integers from 1 to infinity and where s is a complex number. To get an understanding of

detectors‚ including the direct-matrix-inversion (DMI) blind linear minimum mean square error (MMSE) detector‚ the subspace blind linear MMSE detector‚ and the form-I and form-II group-blind linear hybrid detectors‚ are analyzed. Asymptotic limit theorems for each of the estimates of these detectors (when the signal sample size is large) are established‚ based on which approximate expressions for the average output signal-to-interderence-plus-noise ratios (SINRs) and bit-error rates (BERs) are given

Central Limit Theorem The key to the behavior of x-bar is the central limit theorem. It says: Suppose the population has mean‚ m‚ and standard deviation s. Then‚ if the sample size‚ n‚ is large enough‚ the distribution of the sample mean‚ x-bar will have a normal shape‚ the center will be the mean of the original population‚ m‚ and the standard deviation of the x-bars will be s divided by the square root of n.
