It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The trigonometric ratios can be used to solve 3-dimensional problems which involve ...

The cosine rule is: \(a^2 = b^2 + c^2 - 2bc \cos{A}\) This version is used to calculate lengths. Calculate the length BC. Give the answer to three significant figures. Use the form \(a^2 = b^2 + c^2 - ...

Abstract: This article presents an active ball joint mechanism (ABENICS) enhanced by interactions of spherical gears. The gear-based joint drives three rotational degrees of freedom (RDoF) without ...

Abstract: The Terahertz band is envisioned to meet the demanding 100 Gbps data rates for 6G wireless communications. Aiming at combating the distance limitation problem with low hardware-cost, ...

This is a concise Python 3 programming tutorial for people who think that reading is boring. I try to show everything with simple code examples; there are no long and complicated explanations with ...

This project contains code for RabbitMQ tutorials with their ports to various languages. This repository only contains runnable code. Please consult tutorials on the ...

Trigonometric ratios are used to find the unknown side or angle of a right-angled triangle. There are three different trigonometric ratios, \(\sin(\theta), \cos(\theta)\), and \(\tan (\theta)\). Each ...
