find that the trend line that fits the best is the polynomial trend line‚ which is displayed in the graph down below. If we were to analytically develop one model function to determine if the polynomial trend line is indeed the most accurate fit‚ I would propose creating a system of equations. Before jumping to far ahead‚ we need to make it clear the equation we are going to be analyzing. We will use the equation given to us by the polynomial trend line which is: y= ax2 + bx +c and the reason

PROPERTIES OF DISCRETE TIME FOURIER TRANSFORMS ABSTRACT In mathematics‚ the discrete Fourier transform (DFT) converts a finite list of equally-spaced samples of a function into the list of coefficients of a finite combination of complex sinusoids‚ ordered by their frequencies‚ that has those same sample values. It can be said to convert the sampled function from its original domain (often time or position along a line) to the frequency domain. INTRODUCTION The input samples are complex numbers

RATIONAL NUMBERS In mathematics‚ a rational number is any number that can be expressed as the quotient or fraction p/q of two integers‚ with the denominator q not equal to zero. Since q may be equal to 1‚ every integer is a rational number. The set of all rational numbers is usually denoted by a boldface Q it was thus named in 1895 byPeano after quoziente‚ Italian for "quotient". The decimal expansion of a rational number always either terminates after a finite number of digits or begins to repeat the

expression be factored further? Greatest Common Factor A greatest common factor of two or more terms is the largest factor that all terms have in common. The greatest common factor of a polynomial should be factored out first before any further factoring is completed. Example: 3r6+27r4+15r2=3r2(r4+9r2+5) When multiplying variables‚ add the exponents. r^2•r^4=rr•rrrr=r6 When factoring a GCF‚ subtract the exponents. To factor r^2 from r^6: r^6−2=r^4 rrrrrr=(rr)(rrrr)=r2(r4) Difference of Squares Binomials

We also know that the (4 – x)(4 – x) in the new equation can also be foiled to make the next couple of steps easier. “FOIL” consist of multiplying the two‚ two term polynomials together by the first terms‚ the outer
