Code Breakdown: This C++ code generates an array of N_points values for a sine function f(x) = sin(x) and its derivative f'(x). The program then prints out the N_points values of angle, f(x), f'(x), and cos(x). Here is a breakdown of the code: #include<iostream> #include<cmath> using namespace std; #define N_points 300 int main(){ …
The net force on the test charge Q at the center of the regular 12-sided polygon can be found by calculating the vector sum of the forces due to each of the 12 charges q. Since the 12 charges are symmetrically arranged around the center of the polygon, the magnitude of the force on the …
Deferent vs. Epicycle Deferent: A deferent is a large circle that was used by ancient astronomers to explain the motion of planets across the sky. It assumed that all celestial bodies moved around Earth in perfectly circular orbits and so had to account for any irregularities observed from this model. Epicycle: An epicycle is a …

Latitude: Latitude is the horizontal lines through the earth. We get the equator with the concept of Latitude. Longitude: Longitude is the verticle lines through the earth. For more explanation: Imagine our world as a three-dimensional ball. Latitudes are imaginary lines that run from west to east, parallel to the equator. The equator is …
The equator is an imaginary line drawn around the middle of the Earth, halfway between the North and South Poles. It is the reference line from which the Earth’s latitude and longitude are measured and divides the planet into two hemispheres. Facts about the Equator: The equator is an arbitrary line that divides the earth …
A constellation is a group of stars that form a recognizable pattern when viewed from Earth. Some constellations have been known since ancient times, while others were only discovered recently. In astrophysics, constellations are used to understand and chart the night sky. They are important for navigation and locating celestial objects such as planets, stars, …

A comet is a small celestial body made up of ice, dust, and various gases. They typically have a relatively small solid nucleus, around which a bright and large coma (a cloud of gas and dust) forms as the comet gets closer to the Sun. The coma can be several hundred thousand kilometers across. As …
Great Circle / Geodesic: Any circle that passes through the center of a sphere is called a Great Circle or Geodesic. Small Circle: Any plane intersecting the sphere but not passing through the sphere is called Small Circle.
