• The Exponential Distribution | Introduction to Statistics

The probability density function is f(x) = me –mx. The number e = 2.… It is a number that is used often in mathematics. Scientific calculators have the key "e x." If you enter one for x, the calculator will display the value e. The curve is: f(x) = 0.25e –0.25x where x is at least zero and m = 0.25.

• 2 Complex Functions and the Cauchy-Riemann Equations

In one-variable calculus, we study functions f(x) of a real variable x. Like-wise, in complex analysis, we study functions f(z) of a complex variable z2C (or in some region of C). Here we expect that f(z) will in general take values in C as well. However, it will turn out that some functions are

Descartes's rule of signs says the number of positive roots is equal to changes in sign of f(x), or is less than that by an even number (so you keep subtracting 2 until you get either 1 or 0).Therefore, the previous f(x) may have 2 or 0 positive roots..
