## What is an example of induction in science?

Here’s an example of induction: Suppose I have taken 20 marbles at random from a large bag of marbles. Every one of them turned out to be white. That’s my observation – every marble I took out was white. I could therefore form the hypothesis that this would be explained if all the marbles in the bag were white.

**What is the use of mathematical induction in real life?**

Answer: First standard example is falling dominoes. In a line of closely arranged dominoes, if the first domino falls, then all the dominoes will fall because if any one domino falls, it means that the next domino will fall, too.

**Is mathematical induction difficult?**

This could be one reason why mathematical induction is so difficult for students—often times the proposition to be proved is algebraic and not readily converted to a visual representation. This is definitely true of statements like: 2n! > 5n +1 and (7)(8)+(7)(8^2)+…

### What is the first step of mathematical induction?

Step 1 − Consider an initial value for which the statement is true. It is to be shown that the statement is true for n = initial value. Step 2 − Assume the statement is true for any value of n = k. Then prove the statement is true for n = k+1.

**What does == mean in maths?**

== is an logic operator and it is requesting a boolean it should not be confused with = which is used to for example set a value to a variable. You can use == to set a condition like already described from the other comments. So it is used for testing if to values are equal(works for each datatype).

**What does == mean in math?**

When we wish to make a comparison, such as in an if statement, we use the double equals sign (==). A simple example would be the following if ( a == b ) then System.

## What does 2 dots mean in math?

A pair of overdots placed over a symbol, as in , most commonly used to denote a second derivative with respect to time, i.e., .
