Riemann sum

A Riemann sum is a method used in calculus to approximate the integral (or area under a curve) of a function. It is named after the German mathematician Bernhard Riemann. The basic idea behind a Riemann sum is to break up the region under a curve into small rectangles, compute the area of each rectangle, and then sum those areas to approximate the total area under the curve.

PySpark: selecting and accessing data

The content outlines various PySpark functions used for data manipulation in DataFrames. Key functions include filtering with where(), limiting rows with limit(), returning distinct rows, dropping columns, and grouping by criteria. Each function includes a brief example, illustrating how to access, modify, and aggregate data effectively within PySpark.

Integral: How to weight an elephant?

L??ng Th? Vinh, a renowned scholar, ingeniously weighed an elephant by using water displacement, showcasing his mathematical brilliance. His method relates to integration, which sums small quantities to determine total weight, underlying the connection between math and practical problem-solving.

PySpark data frame creation song

This song and example code help remember PySpark data frame creation functions easier. Key functions include creating Data Frames, displaying data, printing schemas, and filtering. The document facilitates understanding how to manipulate data effectively in PySpark, making it a useful reference for users working with large datasets.

pandas function song – grouping the data

This song and code examples help us understand and remember various Pandas functions for data manipulation, including grouping, aggregating, and transforming data. Key functions include groupby(), pivot_table(), resample(), rolling(), expanding(), cumsum(), cumprod(), cut(), qcut(), aggregate(), and transform().

normal distribution song

This song helps us better remember the properties of the normal distribution. A normal distribution, also known as a Gaussian distribution, is a symmetrical, bell-shaped continuous probability distribution characterized by its mean (?) and standard deviation (?). It exhibits properties such as symmetry, unimodality, and follows the 68-95-99.7 rule, indicating the distribution of data within standard deviations of the mean.

Pandas function song

A cute, catchy song on various Pandas functions applied to DataFrames. Key functions include sorting values, resetting the index, dropping columns and duplicates, sampling data, and handling missing values. Example codes illustrate each function’s output, demonstrating how to manipulate and visualize data effectively with Pandas.

Can sound crack glass?

Sounds can crack glass when they match its resonant frequency and are loud enough, typically over 100 decibels. Famous singers like Enrico Caruso and Ella Fitzgerald demonstrated this phenomenon. The process involves amplifying vibrations until the glass can no longer withstand the stress, leading to cracking or shattering.
