Unit Circle: DefinitionThe unit circle is a circle with a radius of one unit.The unit circle is fundamentally related to the concepts of trigonometry. The trigonometric functions can be defined using the unit circle.A unit circle on the Cartesian plane is shown below. It has its center at ...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
What is a Unit Cell? - The unit cell must construct the Bravais lattice by repeating itself in space. However, nothing is said about the number of points that must be contained within the unit cell. Lithium metal crystallizes in a body centered cubic cry

Candela (cd).Unit of luminous intensity. The value of the candela is now based on the luminous efficacy of monochromatic radiation of frequency 540 × 1014Hz, which is 683 lm/W. Prior to 2018, the candela was the measure of electromagnetic radiation, in a specified direction, that had an...
Definition of the trigonometric functionsSuppose you have a right-angled triangle such as the one you see below. Notice that the hypotenuse is the longest side of the triangle.There are six basic trigonometric functions that are commonly used to solve problems. These are sine function, cosine ...
Circle Theorems:Geometry being one of the integral segments of mathematics, holds a good number of theorems and properties. The study of 'Circle' is one of the basics amongst them. Hence, to know all about it's nature and properties, is one of the most important step towards understanding ...
