However, if we put a logarithm there we also must put a logarithm in front of the right side. This is commonly referred to as taking the logarithm of both sides. This is easier than it looks. It works in exactly the same manner here.

The exponential distribution is mostly used for testing product reliability.

The exponential often models waiting times and can help you to answer questions like: If you assume that the answer to these questions is unknown, you can think of the elapsed time as a random variable with an exponential distribution as long as the events occur continuously and independently at a constant rate.

The exponential distribution can model area, as well as time, between events. Young and Young give an example of how the exponential distribution can also model space between events instead of time between events.

Say that grass seeds are randomly dispersed over a field; Each point in the field has an equal chance of a seed landing there.

Now select a point P, then measure the distance to the nearest seed. This distance becomes the radius for a circle with point P at the center.

In other words, if you continue to wait, the length of time you wait neither increases nor decreases the probability of an event happening. Any time may be marked down as time zero. The probability of another hurricane hitting in one week, one month, or ten years from that point are all equal.

The exponential is the only distribution with the memoryless property.

Because of the memoryless property, the probability of a pet dog dying at age 1 would be the same as the dog dying at age 15, which is obviously nonsensical. Therefore, you should think about whether the exponential makes sense logically to your particular area of interest.

For lifetime studies, the exponential is usually used only as a first rough model for the process. The most common form of the pdf is:If you know two points that fall on a particular exponential curve, you can define the curve by solving the general exponential function using those points.

In practice, this means substituting the points for y and x in the equation y = ab x. Powers of Ten or exponential notation on a scientific calculator.

In science, we deal with numbers that are sometimes extremely large or extremely small. In this section we will introduce exponential functions. We will be taking a look at some of the basic properties and graphs of exponential functions.

We will also discuss what many people consider to be the exponential function, f(x) = e^x.

Voiceover:Let's say that we've got the function y is equal to five times two to the t power. Someone were to come up to you and say, "Hey look, this is an interesting function.". *The Greatest Integer Function, sometimes called the Step Function, returns the greatest integer less than or equal to a number (think of rounding down to an integer).

e is NOT Just a Number. Describing e as “a constant approximately ” is like calling pi “an irrational number, approximately equal to ”. Sure, it’s true, but you completely missed the point.
