mathematics." This is because these three basic arithmetic operations occur exactly once each: addition‚ multiplication‚ and exponentiation. The identity also links five fundamental mathematical constants: the number 0‚ the number 1‚ the number π‚ the number e and the number i. But the question remains: how does plugging in pi for x give us -1? Why and how does the Euler’s formula work? So let’s get down to the details. When I saw this formula‚ I immediately started to think of analogies that could help

Logarithmic and exponential functions are often used together because they are inverse functions‚ and therefore “undo” one another. The natural exponential function and the natural logarithm are frequent examples. These functions have a base of the constant e‚ or Euler’s number. The natural exponential function is written as f(x)=ex. Its inverse‚ the natural logarithmic function‚ is written as f(x)=ln(x). The decay of radioactive substances can be represented by using an exponential function. The mass of

A function is a relation in which each element of the domain is paired with exactly one element in the range. Two types of functions are the exponential functions and the logarithmic functions. Exponential functions are the functions in the form of y = ax‚ where ’’a’’ is a positive real number‚ greater than zero and not equal to one. Logarithmic functions are the inverse of exponential functions‚ y = loga x‚ where ’’a’’ is greater to zero and not equal to one. These functions have certain differences

it was widely praised by both blacks and whites‚ although it was not long before critics of Washington’s position emerged to challenge his leadership. Early complaints about Washington’s accommodation to the white South came from the black scholar W. E. B. Du Bois and others. But until he died in 1915‚ Washington was the most influential black leader in America‚ and the most famous black celebrity in the country‚ an adviser to presidents and representative to European heads of state.

Electronic Business E-business (electronic business)‚ derived from such terms as "e-mail" and "e-commerce‚" is the conduct of business on the Internet‚ not only buying and selling but also servicing customers and collaborating with business partners. One of the first to use the term was IBM‚ when‚ in October‚ 1997‚ it launched a thematic campaign built around the term. Today‚ major corporations are rethinking their businesses in terms of the Internet and its new culture and capabilities. Companies

EXPONENTIAL AND LOGARITHMIC FUNCTIONS I.EXPONENTIAL FUNCTION A. Definition An exponential function is a function defined by f(x) = ax ‚ where a > 0 and a ≠ 1. The domain of the function is the set of real numbers and the range is the set of positive numbers. B. Evaluating Exponential Functions 1. Given: f(x) = 2x‚ find a. f(3) = ____ b. f(5) = _____ c. f(-2) = ______ d. f(-4) = ______ 2. Evaluate f(x) = ( 1)x if 2 a. x = 2 ____ b. x = 4 _____ c. x = -3 ______ d
