A set of real numbers used in place of a variable (x, y, z, etc…) is called the domain. Real numbers are used in place of variables to assist in the functionality of the equations. This excludes any real number that causes the denominator to be zero. The reason a denominator cannot be zero is because when we divide the denominator with the numerator, you cannot divide by zero. You can’t have a value that is undefined. The two problems that I was assigned are as follows: 1-x2x 2b-22b2-8

of data. That’s why we love Excel so much. With a few little functions we can take a massive range of data, mine a wealth of information out of it, and turn the data into informed action items. Of course, the thought of trying to string together complex functions in Excel is enough to send anybody into a cold sweat. We couldn’t provide the depth of data or the level of insight offered in our reports without our awesome team of data Analysts who bring it all together. That’s why we asked them to walk

Leonhard Euler, the formula establishes the deep relationship between trigonometric functions and complex exponential functions. According to the formula, for any real number x, In the above formula, e is the base of the natural logarithm, i the imaginary unit. Cos and Sin are trigonometric functions (the arguments are to be taken in radians and not degrees.). The formula applies even if x is a complex number. Particularly with x = π, or half a turn around the circle, e^iπ = cos π + i sin

Zac Bublitz Views of the Status of Women Throughout his letters to Heloise, Abelard emphasizes the importance and significance of intention within the body, heart and soul as opposed to physical actions and deeds. To Abelard, a person is defined more correctly by his or her true desire, feelings and intention spiritually in addition to his or her actions, rather than what he or she might say or appear to be. Abelard keeps true to this belief while considering the status of women. On the contrary

single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number is a complex number with zero imaginary part. PROOF: This is an algebraic proof. I am doing this for a 2 degree polynomial . It can be extended for any degree polynomial. We know that the roots of a quadratic equation az 2 + bz + c = 0 are given by the formula irrespective of the fact whether a, b, c are real or complex numbers. Also it is clear

This is an essay about nothing in order to qualify for this site it must contain at least 250 words. So On the left-hand side above is the exponential statement "y = bx". On the right-hand side above, "logb(y) = x" is the equivalent logarithmic statement, which is pronounced "log-base-b of y equals x"; The value of the subscripted "b" is "the base of the logarithm", just as b is the base in the exponential expression "bx". And, just as the base b in an exponential is always positive and not equal
