    E^x
In summary, the number e is a mathematical constant that represents exponential growth and decay in equations. Its formula is e^x, which results in a smooth curve with a horizontal asymptote. In calculus, e^x is important because it is the only function equal to its own derivative. This makes it useful for solving differential equations and understanding rates of change. In real-life applications, e^x is used in compound interest, population growth, and other scientific fields to predict outcomes and describe natural phenomena.

You should know that

$$\lim_{z \rightarrow \infty} \left( 1+\frac{1}{z}\right) ^z =e$$

Your result follows from it

is there some sort of proof? or should i take it as it is for now?edit: nevermind, i read e on wikipedia.
 

FAQ: Understanding the Limit of [1 + (1/z)]^z as z Approaches Infinity

How does the number e relate to exponential functions?

The number e is a mathematical constant that is approximately equal to 2.71828. It is the base of natural logarithms and is used to represent exponential growth and decay in many scientific and mathematical equations.

What is the formula for calculating e^x?

The formula for e^x is e raised to the power of x, which can also be written as exp(x). This means that e is multiplied by itself x times, resulting in an exponential growth or decay depending on the value of x.

How does the graph of e^x look like?

The graph of e^x is a smooth, continuous curve that starts at the point (0,1) and increases rapidly as x increases. It has a horizontal asymptote at y=0, meaning that the curve will never touch or cross the x-axis.

Why is e^x important in calculus?

e^x is important in calculus because it is the only function that is equal to its own derivative. This property makes it a useful tool for solving differential equations and understanding rates of change in continuous systems.

How is e^x used in real-life applications?

e^x is used in many real-life applications, such as compound interest calculations, population growth models, and radioactive decay equations. It also has applications in physics, chemistry, and biology to describe natural phenomena and predict future outcomes.
