The function f(x) = ax² + bx + c is called the quadratic expression. If a and b are the two distinct roots of the quadratic expression (or) A quadratic equation is an equation where the highest power of x is x². The standard form of quadratic equation is ax² + bx + c = Read more about Quadratic Expression[…]
When any object is moved then its speed is changed which is called velocity while the change in velocity is acceleration. When it is changed continues then it is in accelerating condition which is called the rate of acceleration. It is equal to the ratio of change in velocity with respect to time between the given paths. The vector Read more about Acceleration Due to Gravity[…]
What is V-SAT? Vignan’s Scholastic Aptitude Test (V-SAT) is conducted on all India basis for admission into B.Tech. in Vignan’s University at its Vadlamudi, Guntur Campus, Andhra Pradesh, India. Eligibility Criteria for Admission: Candidates born on or after 1st July, 1997 and a pass in Intermediate or its equivalent with minimum 60% aggregate marks are Read more about Vignan’s Scholastic Aptitude Test (V-SAT) 2018 Notification Released[…]
Mathematical Statement: A mathematically acceptable statement is a sentence which is either true or false but not both. For example, Two plus two equals four. The sum of two positive numbers is positive. All prime numbers are odd numbers. Of these sentences, the first two are true and the third one is false. Compound Statement: If Read more about Mathematical Reasoning[…]
Potential energy is the ability of an object to store energy based on its position. For example, if you stretch a rubber band, to the farthest point energy will be stored in the object based on its position. The same thing happens when a wrecking ball is used to demolish buildings. The definition for gravitational Read more about Gravitational Potential Energy[…]
Relation: For any non-empty sets A and B, a subset of A × B is called a relation from A to B. Example: A relation assigns the x’s with y’sThis relation can be written as {(1, 6), (2, 2), (3, 4), (4, 8), (5, 10)} Example: A x B = {{a, x), (b, x), (c, x), (a, Read more about Relations and Functions[…]
Sir Isaac Newton gave a mathematical relation to calculate the force of gravitation and this relation is known as the universal law of gravitation. It is a common belief that an apple fell on Newton’s head and he realized that gravity exists. This isn’t completely incorrect. But Newton already knew about the existence of gravity. Read more about Universal Law of Gravitation[…]
In three dimensions, the coordinate axes of a rectangular Cartesian co-ordinate system are three mutually perpendicular lines. The axes are called the x, y and z axes. Co-ordinates of a Point: The coordinates of a point P in three-dimensional geometry is always written in the form of triplet like (x, y, z). Here x, y Read more about Three-Dimensional Geometry[…]
This is applicable only to a plane lamina. The moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of the moments of inertia of the lamina about any two mutually perpendicular axes, passing in its own plane, intersecting each other at the point through which Read more about Perpendicular Axis Theorem[…]
In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse.Conic section consists of those points whose distances to some point (called focus) and some line (called directrix) are in a fixed ratio, called the eccentricity.
