    Table
In summary, a table of primitives is a data structure used to store primitive data types in a tabular form for efficient data organization and retrieval. Scientists use them for data storage and analysis purposes, and they are created by determining the data types and using programming languages to initialize the table. The main difference between a table of primitives and a table of objects is that the latter can store more complex data structures and is typically slower and less memory-efficient. Tables of primitives are commonly used in scientific research for data storage, organization, and analysis, as well as for data visualization and statistical calculations.

Hi, I'm looking for an ONLINE table of primitives. Does anybody know of a good website?

Thanks

Or for now, does anybody know what this integral is

[tex]
\int \frac{sinx}{\sqrt{1 + 3sin^2x}}dx
[/tex]

?

Let u = cos(x)

?!

That's not it. We're still stuck with the square root.

It is indeed "it".

If u = cos(x), then u^2 = cos^2(x) = 1 - sin^2(x) (etc)... The "new" integral can be handled with an inverse trigonometric function.

That's genius! Thanks both of you!

I'm still interested in a table of primitive though ;)
 

1. What is a table of primitives?

A table of primitives is a data structure that stores a collection of primitive data types, such as integers, floating-point numbers, and characters, in a tabular form. It is used to efficiently organize and retrieve data in computer programs.

2. Why do scientists use tables of primitives?

Scientists use tables of primitives because they provide a simple and efficient way to store and access large amounts of data. This is especially useful for data analysis and statistical calculations.

3. How do you create a table of primitives?

To create a table of primitives, you first need to determine the data types you want to store and the number of rows and columns in the table. Then, you can use programming languages like Java or Python to declare and initialize the table with the desired data.

4. What is the difference between a table of primitives and a table of objects?

A table of primitives stores only basic data types, while a table of objects can store more complex data structures, such as arrays, strings, and custom objects. Additionally, a table of primitives is typically faster and more memory-efficient compared to a table of objects.

5. How are tables of primitives used in scientific research?

Tables of primitives are commonly used in scientific research for data storage, organization, and analysis. They can be used to store experimental results, observational data, and other types of scientific data. They are also used in data visualization and statistical analysis to help researchers draw conclusions and make predictions based on the data.
