Differential Equations as Mathematical Models-Falling bodies

In this topic, we formulate and solve a number of differential equations that originate from real-world problems. Example 1 A ball of mass m is thrown straight up from the ground with an initial velocity of v_{0} . Ignoring air resistance, find the maximum height and the time the ball takes to attai...

Mean, Standard Deviation and Variance

Mean Mean is the average value. This means, mean is the value obtained by summing all the values in the dataset of your interest and divide by the number of values in the dataset. Mean is usually the central value, which divides the distribution into two equal halves. Suppose you have the following...

How to Install and Test Python Healpy in Ubuntu Linux

We are going to show you how to install the HEALPix distribution. HEALPix is a shorthand for Hierarchical Equal Area isoLatitude Pixelation of a sphere. As the name suggests, this pixelation produces a subdivision of a spherical surface whereby each pixel covers the same surface area as every other ...
